Monolithic Digital IC
LB11823M
Direct PWM Drive Brushless Motor Predriver
for OA Products
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.
