Overview

The LB11651 is a full bridge driver that supports switching between forward and reverse directions. It operates in one of four modes under application control: forward, reverse, brake, and open. It also supports direct PWM control from an external signal. The LB11651 is optimal for driving brush DC motors and bipolar stepping motors.

Features

• Supports PWM input

• Built-in high and low side diodes

• Simultaneous on state prevention function (prevents through currents)

• Built-in thermal shutdown circuit (latching type)

• High and low side short circuit protection function (latching type overcurrent protection)

• Externally controllable modes: forward, reverse, brake, open

• Standby mode function
