Overview
The LB11650H 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
