DRV8837DSGR Description

The DRV8837DSGR  provides an integrated motor driver solution for cameras, consumer products, toys, and other low-voltage or battery-powered motion control applications. 

The DRV8837DSGR IC can control one dc motor as well as additional devices such as solenoids. To drive the motor winding, the DRV8837DSGR block output consists of N-channel power MOSFETs configured as an H-bridge. Gate drive voltages are generated by an internal charge pump.

The DRV8837DSGR has a maximum output current of 1.8 A. A motor power supply voltage of 0 to 11 V and a device power supply voltage of 1.8 V to 7 V is used by the DRV8837DSGR motor driver.
