两个逻辑输入控制H 桥驱动器，该驱动器由四个N 沟道金属氧化物半导体场效应晶体管(MOSFET)组成，能够以高达3.6A 的峰值电流双向控制电机。
利用电流衰减模式，可通过对输入进行脉宽调制(PWM)来控制电机转速。
如果将两个输入均置为低电平，则电机驱动器将进入低功耗休眠模式。
DRV8871器件具有高级电流调节电路，该电路不使用模拟电压基准或外部感应电阻器。
这种新型解决方案采用标准的低成本、低功耗电阻来设置电流阈值。
该器件能够将电流限制在某一已知水平，这可显著降低系统功耗要求，并且无需大容量电容来维持稳定电压，尤其是在电机启动和停转时。
该器件针对故障和短路问题提供了全面保护，包括欠压锁定(UVLO)、过流保护(OCP)和过热保护(TSD)。

经典分立元件H桥驱动电机专用（稳定、低成本，经典分立元件H桥驱动电机专用(稳定、低成本，经典分立元件H桥驱动电机专用(稳定、低成本，可代替IR21XX集成IC驱动) 测试结果Mos IRF2807不如改用STP75NF75，所有的关键指标都比2807强，而且也是75V 80A级别的。
D2PAK的也能买到，价格应该和2807差不多。
本电路是在48V直流电机驱动上使用非常普遍的分立元件MOS管驱动电路，适用频率可达30kHz左右，稳定可靠，在成本局限的产品上可代替IR21XX驱动IC。
这个电路已经经历了多年的商业化检验，保证你按照电路里的参数制作就可正常工作。
制作时要注意以下几点:1)如果你的电机工作电压低于等于12V可能需要调整上桥臂晶体管的工作状态。
2)自举电容C5 C6要使用低漏电的。
3)D5 D6如成本允许应使用快恢复型二极管如FR157。
4)主滤波电容C11 C12必须是高频低阻电容，否则纹波容易引起发烫。
5)C9 C10耐压应是电源的至少一倍。
6)注意布线～～～尤其是高频部分(参考IR的一系列布线文档) 7)由于使用了自举电路，启动时必须先开下桥再开上桥(PWM只能在下桥上加，上桥只加开关信号);而且PWM不能大于95%，否则重载启动、短路测试时烧你没商量(这点连IR21XX也是一样)。
这个驱动稳定，目前电动车控制器里用的基本上都是这个电路。
实验室测的有堵转启动、堵死启动、运行时短路相线、启动时短路相线。
工业化生产时一般只抽检不做全检。
序流程很简单:1.上电初始化，H桥四个输入端均为高电平。
【启动电机】1.获得启动电机命令后先打开下桥2，输出80%占空比的PWM(因为本H桥驱动是低电平开启，80%PWM实际为100%-80%=20%)2.四到八个PWM周期延迟后打开上桥1(延迟不必控制得很严格)3.如设定转速应高于20%占空比PWM的转速，在半秒内逐渐增加下桥2PWM至设定的PWM(如设定电机应全速运转，则由最初80%占空比PWM逐渐降低至5%) 注:反转则为开上桥1-下桥2，过程相同不再复述。

In sleep mode, the H-bridge FETs are disabledPOWER SUPPLY RECOMMENDATIONSHaving appropriate local bulk capacitance is an important factor in motor-drive system design. It is generally beneficial to have more bulk capacitance.The amount of local bulk capacitor needed depends on the following factors ,∙The highest current required by the motor system.∙The power-supply capacitance and ability to source current∙The amount of parasitic inductance between the power supply and motor system∙The acceptable voltage ripple∙The type of motor used (brushed dc, brushless dc, stepper)∙The motor braking methodThe inductance between the power supply and motor drive system limits the rate at which current can change from the power supply. If the local bulk capacitance is too small, the system responds to excessive current demands or dumps from the motor with a change in voltage. When adequate bulk capacitance is used, the motor voltage remains stable and high current can be quickly supplied.The voltage rating for bulk capacitors should be higher than the operating voltage, to provide margin for cases whenFigure 3. Motor Driver System with External Power SupplyPCB LAYOUTThe VM and VCC should be bypassed to GND using low-ESR ceramic capacitors with recommended value of 0.1µF. These capacitors should be placed as close to the VM and VCC as possible with a thick trace or ground plane connection to GND.0.1uF0.1uFELECTRICALCHARACTERISTICSTIMING REQUIREMENTST A =25℃IN1IN2OUT1OUT2OUTxTYPICAL OPERATING CHARACTERISTICSFigure 12. 50% Duty Cycle , Forward Direction Figure 13. 20% Duty Cycle , Forward Direction Figure 14. 50% Duty Cycle , Reverse Direction Figure 15. 20% Duty Cycle , Reverse DirectionPACKAGE INFORMATION 8-PIN, DFNNote:Refer to JEDEC MO-2298 PINS, SOP, 150MILNotes:1.
