bq20z80supports a wide range of battery and system protection features that can easily be configured.The primary safety features includes:•Battery cell over/under voltage protection •Battery pack over/under voltage protection •2independent charge overcurrent protection •3independent discharge overcurrent protection •Short circuit protection•Over temperature protection •Host watchdogThe secondary safety features of the bq20z80can be used to indicate more serious faults via the SAFE (pin 7)and SAFE (pin 12)pins.These pins can be used to blow a in-line fuse to permanently disable the battery pack from charging or discharging.The secondary safety features includes:•Safety over voltage •Battery cell imbalance•2nd level protection IC input •Safety over current•Safety over temperature •Open thermistor•Charge FET and 0Volt Charge FET fault •Discharge FET fault•Fuse blow failure detection •AFE communication error •Internal flash data errorThe bq20z80charge control features includes:•Report the appropriate charging current needed for constant current charging and the appropriate charging voltage needed for constant voltage charging to a smart charger using SMBus broadcasts.•Determines the chemical state of charge of each battery cell using Impendance Track™and can reduce the charge difference of the battery cells in fully charged state of the battery pack gradually using cell balancing algorithm during charging.This prevents fully charged cells from overcharging causing excessive degredation and also increases the usable pack energy by preventing to

Functionbq20z80-V102SLUS681B–NOVEMBER2005–REVISED JANUARY2007 FEATURE SET(continued)The bq20z80uses the Impedance Track™Technology to measure and calculate the available charge in battery cells.The archievable accuracy is better than the coloumb counting method over the lifetime of the battery and there is no full charge discharge learning cycle required.See Theory and Implementation of Impedance Track Battery Fuel-Gauging Algorithm application note (SLUA364)for further details.The bq20z80can drive3-,4-,or5-segment LED display for remaining capacity indication.The bq20z80offers a lifetime data logging array,where all important measurements are stored for warranty and analysis purposes.The data monitored includes:•Lifetime maximum temperature•Lifetime minimum

current•Lifetime maximum discharge current•Lifetime maximum charge power•Lifetime maximum discharge power•Lifetime maximum average discharge current•Lifetime maximum average discharge power•Lifetime average temperatureThe bq20z80supports authentication by the host using SHA-1.The bq20z80supports3different power modes to reduce power consumption:•In Normal Mode,the bq20z80performs measurements,calculations,protection decicions,data update in1 second intervals.Between these intervals,the bq20z80is in a reduced power stage.•In Sleep Mode,the bq20z80performs measurements,calculations,protection decicions,data update in adjustable time intervals.Between these intervals,the bq20z80is in a reduced power stage.•In Shutdown Mode the bq20z80is completety disabled.The oscillator of the bq20z80can be set up for internal or external operation.On power up,the bq20z80 automatically attempts to start the internal oscillator.If a100-kΩresistor is not connected to ROSC(pin33), then it attempts to start the oscillator using an external32.768-kHz crystal.NOTE:Install either the100-kΩROSC resistor or the12-pF,32.768-kHz crystal.Do notinstall both.9Submit Documentation FeedbackSystem Present OperationBATTERY PARAMETER MEASUREMENTSCharge and Discharge CountingVoltageCurrentAuto CalibrationTemperatureCOMMUNICATIONSSMBus On and Off Statebq20z80-V102SLUS681B–NOVEMBER 2005–REVISED JANUARY 2007FEATURE SET (continued)The performance of the internal oscillator depends on the tolerance of the 100-k Ωresistor between RSOC (pin 33)and VSSA (pin 34).Choose a resistor with a tolerance of ±0.1%,and 50-ppm or better temperature drift.Place this resistor as close as possible to the bq20z80.If a 12-pF crystal is used,place it as close as possible to the XCK1(pin 34)and XCK2(pin 33)pins.If not properly implemented,the PCB layout in this area can degrade oscillator performance.The bq20z80pulls the PU pin high periodically (1s).Connect this pin to the PRES pin of the bq20z80via a resistor of approximately 5k Ω.The bq20z80measures the PRES input during the PU-active period to determine its state.If PRES input is pulled to ground by external system,the bq20z80detects this as system present.The bq20z80uses an integrating delta-sigma analog-to-digital converter (ADC)for current measurement,and a second delta-sigma ADC for individual cell and battery voltage,and temperature measurement.The integrating delta-sigma ADC measures the charge/discharge flow of the battery by measuring the voltage drop across a small-value sense resistor between the SR1and SR2pins.The integrating ADC measures bipolar signals from -0.25V to 0.25V.The bq20z80detects charge activity when V SR =V (SR1)-V (SR2)is positive and discharge activity when V SR =V (SR1)-V (SR2)is negative.The bq20z80continuously integrates the signal over time,using an internal counter.The fundamental rate of the counter is 0.65nVh.The bq20z80updates the individual series cell voltages through the bq29312A at one second intervals.The bq20z80configures the bq29312A to connect the selected cell,cell offset,or bq29312A VREF to the CELL pin of the bq29312A,which is required to be connected to VIN of the bq20z80.The internal ADC of the bq20z80measures the voltage,scales and calibrates it appropriately.This data is also used to calculate the impedance of the cell for the Impedance Track™gas-gauging.The bq20z80uses the SR1and SR2inputs to measure and calculate the battery charge and discharge current using a 5m Ωto 20m Ωtyp.sense resistor.The bq20z80provides an auto-calibration feature to cancel the voltage offset error across SR1and SR2for maximum charge measurement accuracy.The bq20z80performs auto-calibration when the SMBus lines stay low continuously for a minimum of 5s.The bq20z80TS1and TS2inputs,in conjunction with two identical NTC thermistors (default are Semitec 103AT),measure the battery environmental temperature.The bq20z80can also be configured to use its internal temperature sensor.The bq20z80uses SMBus v1.1with Master Mode and package error checking (PEC)options per the SBS specification.The bq20z80detects an SMBus off state when SMBC and SMBD are logic-low greater than an adjustable period of time.Clearing this state requires either SMBC or SMBD to transition high.Within 1ms,the communication bus is available.10Submit Documentation FeedbackSBS and Dataflash ValuesSLUS681B–NOVEMBER2005–REVISED JANUARY2007 FEATURE SET(continued)Table1.SBS COMMANDSSBS Cmd Mode Name Format Size
