The UTC MD8837 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 7.0 V.

The UTC MD8837 provides an integrated motor driver solution.

The device can drive one DC motor or other devices like solenoids.

The output driver block consists of N-channel power MOSFET’s

configured as an H-bridge to drive the motor winding. An internal

charge pump generates needed gate drive voltages.

The UTC MD8837 has a PWM (IN1/IN2) input interface.Both

interfaces are compatible with industry-standard devices.
