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; th...
