[原创] TI DRV8837直流马达驱动解决方案

TI公司的DRV883x是H桥马达驱动器系列产品,能驱动DC马达或其它负载,输出部分包括N沟功率MOSFET,驱动电流最大为1.8A, PWM或PH/EN接口,内置的保护包括过流保护,短路保护,欠压锁住和超温保护.主要用在IP网络监视照相机,气表,低压马达控制和水表.本文介绍了DRV8837主要特性,功能框图, DRV883评估模块(EVM)主要特性,电路图和材料清单.

The DRV883x provides an integrated motor driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion control applications. The device can drive one DC motor or other devices like solenoids. The output driver block consists of N-channel power MOSFET’s configured as an H-bridge to drive the motor winding. An internal charge pump generates needed gate drive voltages.

The DRV883x can supply up to 1.8 A of output current. It operates on a motor power supply voltage from 0 to 11 V, and a device power supply voltage of 1.8 V to 7.0 V.

The DRV8837 has a PWM (IN/IN) input interface; the DRV8837 has a PH/EN input interface. Both interfaces are compatible with industry-standard devices.

Internal shutdown functions are provided for overcurrent protection, short circuit protection, undervoltage lockout, and overtemperature.

DRV8837主要特性:
