After the battery is full, get off the adapter . And then we can boost up to 5V to charge the mobile advices when they is empty.Li-Battery Charger can set charge current by PROG resistor. Normal charging current is set from 0.5A to 1A. It will go into trickle charge mode to protect Li-Battery when BAT voltage is below 2.9V. Li-Battery Protection can detect the battery cell’s status such as Vcu 、Vcl ,Temp 、short-cut 、Over-current and take action to protect battery cell.Boost section can give us 5V 1A capacity to mobile devices.THERMAL OR SHORT-CUT PROTECTIONA thermal shutdown is implemented to prevent damages due to excessive heat and power dissipation. Typically the thermal shutdown threshold is 150℃ .When the thermal shutdown is triggered the device stops switching until the temperature falls below typically 136℃.Then the device starts switching again.If the Boost converter’s Vout is short to GND ,the IC will shut down and you should recharge the battery to get rid of this status.CHEN 、BSEN voltage Ven0.3 1 1.5VRecharge Battery threshold VoltageΔVrecg V FLOAT - V RECHRG 100 200mV Overcharge DetectionVoltage of Li BAT-Protection V CU 4.225 4.25 4.275V Overcharge Release Voltage of Li BAT-Protection V CL 4.075 4.10 4.125V Overdischarge DetectionVoltage of Li BAT-Protection V DL 2.85 2.9 2.95VOverdischarge ReleaseVoltage of Li BAT-Protection V DR2.953.0 3.05VOverdischarge Current1 Detection of Li BAT-ProtectionI IOV1 (V B+)-(V B -)=3.5V 2.1 3 3.9 ALoad Short-Circuiting Detection of Li BAT-ProtectionI SHORT (V B+)-(V B -)=3.5V 10 20 30 ABoost output voltage range Vout 20 VRegulated Feedback Voltage V FB1.118 1.2 1.212VPeak Inductor Current I PEAK Rset=150K Vin=3.3V Vout=5V 0.8 1 1.2 A Peak Inductor Current I PEAK Rset=500K Vin=3.3V Vout=5V2.2 2.55 2.9ABoost ConvertOscillator FrequencyF OSC0.9 1.2 1.5MHzAPPLICATION INFORMATIONINDUCTOR SELECTIONIn normal operation, the inductor maintains continuous current to the output. The inductor current has a ripple that is dependent on the inductance value. The high inductance reduces the ripple current.Selected inductor by actual application:Manufa cturer Part Number Inductance (uH) DRC max(Ohms)Dimensions L*W*H(mm3)2.2 0.0493.3 0.0654.7 0.08 LQH44PN10 0.164*4*1.7 2.2 0.0303.3 0.0444.7 0.058 MurataLQH5BP10 0.1065*5*2 2.2 0017 3.3 0.027 TDK SPM6530T4.7 0.0367.1*6.5*3 744373 240222.2 0.0614.4*4.05WURTH 744777004 4.70.0257.3*7.3*4.5Table 1. Recommend Surface Mount InductorsIf output voltage is 5V ,you can use 2.2uH~ 4.7uH, If output voltage is 12V, 4.7uH~ 10uH is OK , Normal application: Input 3.3V (3.6V or 4.2V) to Output 5V 9V 12V ;Input 5V to Output 9V 12VCAPACITOR SELECTIONThe input capacitor reduces input voltage ripple to the converter, low ESR ceramic capacitor is highly recommended. For power bank application, A 10uF ceramic capacitor is used. The input capacitor should be placed as close as possible to CHIN and GND. Such as Murata GRM21BR60J106 or TDK C3216X5R1A106M A low ESR output capacitor is required in order to maintain low output voltage ripple. one 10~22uF ceramic output capacitor is suitable for most applications. Such as GRM21BR60J226 or TDK C3216X5R1A226M B+-Pin 3 should be bypassed with a 1uF capacitor as close as possible , B+-Pin12 should be bypassed with a 10uF capacitor as close as possible.SET CHARGE CURRENTThe charge current is programmed by connecting a 1% resistor, R PROG , PROG pin to ground. When charging in constant-current mode, this pin servos to 1V. In all modes, the voltage on this pin can be used to measure the charge current using the following formula: I charge = (V PROG /R PROG ) •1000.OUTPUT VOLTAGE PROGRAMMINGThe output voltage is set by a resistive divider according to the following equation:Typically choose R2=30K and determine R1 from the following equation:For example, you can select R2=31.5K R1=100K to set 5VoutDIODE SELECTIONAccording to max Iout and max Vout, you can select suitable diode. Normally we select diode If=(1.5~2)*Ioutmax and VR=(1.5~2)*Voutmax. For high efficiency,suggest that you select low Vf Schottky diode.For example, 5V 1Aout power bank application, you can select MBRA210LT3 or SS24. Using MBRA210LT3, you can get higher efficiency.OC SETTING( SETTING CURRENT LIMIT)S5802 can be adjusted SW current limit by one resistor connected with BSOC pin。

If adapter is absent and battery voltage is high enough, the power switch is turned off and G5214 is in boost mode, the boost converter out-puts to system output source from battery. The power switch is turned on after adapter is plugged-in and detected. G5214 turns into charger mode after the power switch is fully turned on. In charger mode, sys-tem output is directly supply from adapter via the power switch, and the charger convertor supply charging current to the battery from system output. There are several protections of power path, boost convertor and charger convertor.Power Path ControlAdapter is detected if VADP is larger than power good threshold (4.74V with hysteresis) and smaller than OVP threshold (5.78V with hysteresis). After the de-tection of adapter, the power switch between VSYS and VADP turns on. The gate of NMOS switch rises slowly to minimize surge current of adapter. There is over-current protection for the power switch. If over-load occurs on VSYS, the switch gate is lowered down to keep the current flow through the switch in current limit to protect adapter and the switch.When adapter input OVP is detected, the power switch is shutdown immediately to keep VSYS below normal voltage range to protect the devices connected to VSYS from damaged by high voltage.After the gate of power switch rises high enough and no abnormal event is detected. The system gets into charger mode. If system isn’t in charger mode and the battery voltage is higher than VBAT UVLO threshold, the system operates in boost mode, otherwise the system is shutdown.Boost ConvertorIn boost mode, VSYS is boosted to the voltage setting by external resistors connected from VSYS to BTFB to GND. The BTFB pin is regulated to 0.61V. The con-troller of boost is constant off-time and the off-time is calculated by VSYS and VBAT to keep the switching frequency near 500kHz. Internal soft-start controls the rising time of VSYS output to about 1ms. There is OVP function of boost output.Boost convertor has current limit functions. If VSYS is lower than VBAT, the inductor current is limited to 2.5A. If VSYS is larger than VBAT, G5214 performs cycle by cycle peak inductor current limit. The current limit value is inversely proportion to VBAT, that makes output current limit changes slightly versus battery voltage.EN/OC pin controls the operation of boost convertor. The current limit is set to 3/4 of normal value when EN/OC is connected to VBAT. The boost convertor is shut down if EN/OC pin is pulled to GND. Leave the pin floating for normal operation.Charger ConvertorIn charger mode, adapter is connected to VSYS as the power of charger for 1 cell Li-lon battery. The system controls the battery voltage to 4.35V, 4.3V or 4.2V for G5214A/G5214D and G5214CG5214F, respectively. The charging current is lower down if adapter current is larger than a preset level. The current limit of total adapter current is 2A or 1.5A and current is sensed by internal resistor. The controller is constant off-time and the off-time is calculated by VSYS and VBAT to keep the switching frequency near 700kHz. The charger convertor is internal compensated.If battery voltage is below the UVLO threshold, the system is trickle charged with 15% of the normal charging current. The battery is determined as dead battery if battery voltage keeps under the UVLO threshold for over 17728S.G5214 has over-voltage protection for charger. The high and low side switched are turned off immediately if battery voltage goes over 4% of normal battery volt-age setting.The charge current is 2A or 1.5A. The adapter current is also limited to 2A or 1.5A. The current limits of power switch is 2.6A or 2.1A.Over-Current ProtectionsThe over-current protection of VSYS pin is auto-restart mode. If any of VSYS OCP event occurs (OCP of power switch or boost convertor) and lasting over 34ms, the system shutdown for 238ms and re-start again. The function keep the system temperature low even if VSYS is short. G5214 also have over-temperature protection. The whole system is shutdown if temperature rises over 150°C.Charger Status FlagWhen G5214 operates in charging mode, FLAG out-puts low if the battery is not fully charged. The FLAG pin outputs high impedance if system is not in charg-ing or the battery is fully charged.Application InformationInductor SelectionInductance between 3.3µH and 10µH is recommended. The RHZ is lower with large inductance. Select smaller inductance with larger VSYS capacitance to enlarge system bandwidth with the same output ripples at boost mode. It’s important to select inductor with maximum current to avoid saturation. Check both charger mode and boost mode for peak current.VSYS Capacitor SelectionThe recommended value of this capacitors is 33µFX2. This value maintain the boost controller loop at proper bandwidth with sufficient phase margin.VBAT Capacitor SelectionConnect 20µF capacitor to maintain charger loop sta-bility and serve as input capacitor at boost mode. Current Sense Resistor SelectionThe charging current and current limit at boost mode are inverse proportion to R SNS. Select 10mΩR SNS for proper current setting. To maintain stability of charger loop, 10mΩ or larger R SNS is recommanded.PCB Layout ConsiderationsSignal Ground and Power Ground ConnectionAt minimum, a reasonably large area of copper, which will shield other noise couplings through the IC, should be used as signal ground beneath the IC. The best tie-point between the signal ground and the power ground is at the negative side of the output capacitor on each side, where there is little noise; a noisy trace beneath the IC is not recommended.LX PinThis trace should be short, and positioned away from other weak signal traces. This node is noisy and has high voltage swing. No trace should be in parallel with it.CSIP, VBAT PinsThese pins is used as the battery voltage and inductor current feedback. The traces should be away from the noisy pins like LX. In general, the current sense resis-tor R SNS should be close to the IC.Copper Size for the LX NodeThe capacitance of LX should be kept very low to minimize ringing. It would be best to limit the size of the LX node copper.Exposed PADIt’s highly recommended to add larger copper to ex-posed PAD connected to signal ground. At high cur-rent operation, the power consumption is high. Large copper to exposed PAD decrease thermal resistance much.Package InformationSOP- 8 (FD) PackageTaping SpecificationPACKAGE Q ’TY/REELSOP-8 (FD)2,500 eaGMT Inc. does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and GMT Inc. reserves the right at any time without notice to change said circuitry and specifications.。
