产品亮点

The DRV8837 provides an integrated motor-driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion-control applications. The device has one H-bridge driver, and can drive one dc motor or one winding of a stepper motor, as well as other devices like solenoids. The output driver block consists of N-channel power MOSFETs configured as an H-bridge to drive the motor winding. An internal charge pump generates needed gate-drive voltages.

DRV8837器件为相机，消费类产品，玩具，和其他低电压，或电池供电的运动控制应用提供了一个集成的，电机驱动解决方案。该器件具有一个H桥驱动器，可以驱动一个直流电动机，或步进电机的一个绕组，以及其他设备，如，螺线管。其输出驱动器部件包括，N-频道功率MOSFET（配置为H电桥，以驱动电机绕组）。其内部电荷泵产生所需要的栅极驱动电压。

The DRV8837 can supply up to 1.8 A of output current. It operates on a motor power-supply voltage from 1.8 V to 11 V, and a device power-supply voltage of 1.8 V to 7 V.

The DRV8837 has a PWM (IN/IN) input interface, which is compatible with industry-standard devices.

There are internal shutdown functions for overcurrent protection, short-circuit protection, undervoltage lockout and overtemperature.

The DRV8837 package is an 8-pin 2-mm × 2-mm WSON PowerPAD package.
