UNISONIC TECHNOLOGIES CO., LTD UMD9137 Preliminary LOW-VOLTAGE H-BRIDGE DRIVER CMOS IC  DESCRIPTION The UTC UMD9137 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 UMD9137 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 UMD9137 has a PWM (IN1/IN2) input interface.Both interfaces are compatible with industry-standard devices.
