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.
Internal shutdown functions are provided for overcurrent
protection, short circuit protection, undervoltage lockout, and
overtemperature.
