Overview
The LB11823M is a direct PWM drive predriver IC for
use with three-phase power brushless motors. The
LB11823M can implement a motor drive circuit with the
desired output capacity (voltage and current) by using
appropriate external transistors. Due to its built-in FG
amplifier and other features, this device is optimal for
motor drive in OA products that use power brushless
motors.
Functions and Features
Three-phase bipolar drive
Direct PWM drive
Built-in FG amplifier and Schmitt comparator circuits
Braking function (short-circuit braking)
Built-in forward/reverse switching circuit
Full complement of built-in protection circuits,
including current limiter, undervoltage protection
circuit, motor lockup protection circuit, and thermal
protection circuit.
Can be controlled by either a command voltage or the
duty of an input PWM signal.
