Overview

The LB11820M is a direct PWM drive pre-driver IC that

is appropriate for 3-phase power brushless motors. This IC

can implement motor driver circuits that provide the

desired output capabilities (voltage and current) by the use

of appropriate discrete transistors in the output circuit. The

LB11820M is optimal for driving the large motors used in

air conditioners and on-demand hot water heaters.

Functions and Features

• Three-phase bipolar drive

• Direct PWM drive

• Built-in braking function (Short braking)

• Forward/reverse switching function

• Reverse motion mode protection circuit

• Full complement of protection circuits, include current

limiter, low-voltage protection, and motor constraint

(rotor locking) protection circuits

• Supports control from either a command voltage or a

PWM duty input.
