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.
