LB11696V
Overview
The LB11696V is a direct PWM drive pre-driver IC designed for three-phase power brushless motors. A
motor driver circuit with the desired output power (voltage and current) can be implemented by adding
discrete transistors in the output circuits. Furthermore, the LB11696V provides a full complement of
protection circuits allowing it to easily implement high-reliability drive circuits. This device is optimal for
driving all types of large-scale motors such as those used in air conditioners and on-demand water heaters.
Function
Three-phase bipolar drive
Direct PWM drive (controlled either by control voltage or PWM variable duty pulse input)
Built-in forward/reverse switching circuit
Start/stop mode switching circuit (stop mode power saving function)
Built-in input amplifier
5V regulator output (VERG pin)
Current limiter circuit (Supports 0.25V (typical) reference voltage sensing based high-precision detection)
Under voltage protection circuit (The operating voltage can be set with a zener diode)
Automatic recovery type constraint protection circuit with protection operating state discrimination output
(RD pin)
Four types of Hall signal pulse output
Supports thermistor based thermal protection of the output transistors
