LB11650

Overview

The LB11650 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 LB11650 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
