MD8837数据手册UTC中文资料规格书

描述 Description

The UTC MD8837 can supply up to 1.8 A of output current. Itoperates on a motor power supply voltage from 0 to 11 V, and adevice 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’sconfigured as an H-bridge to drive the motor winding. An internalcharge pump generates needed gate drive voltages.The UTC MD8837 has a PWM (IN1/IN2) input interface.Bothinterfaces are compatible with industry-standard devices.Internal shutdown functions are provided for overcurrentprotection, short circuit protection, undervoltage lockout, andovertemperature.
