3 Description
The DRV883x family of devices 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 Nchannel
power MOSFETs configured as an H-bridge
to drive the motor winding. An internal charge pump
generates needed gate drive voltages.
The DRV883x family of devices 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 V.
The DRV8837 device has a PWM (IN1-IN2) input
interface; the DRV8838 device 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.
