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 N- channel 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.
