DRV8837 - 1.8A Low Voltage Brushed DC Motor Driver (PWM CTRL)

Picture for category DRV8837 - 1.8A Low Voltage Brushed DC Motor Driver  (PWM CTRL)

12 September 2017

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.

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.

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

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