3 Description
The DRV8837C device 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 MOSFETs
configured as an H-bridge to drive the motor winding.
An internal charge pump generates needed gate
drive voltages.
The DRV8837C device can supply up to 1 A of output
current. The device operates on a motor power
supply voltage from 0 to 11 V, and control logic can
operate on 1.8-V to 5-V rails.
The DRV8837C device has a PWM (IN/IN) input
interface.
Internal shutdown functions are provided for
overcurrent protection, short circuit protection,
undervoltage lockout, and overtemperature.
