LB11696V Direct PWM Drive Brushless Motor
Predriver IC
Overview
The LB11696V is a direct PWM drive predriver 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.
Functions and Features
• 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
• 5 V regulator output (VREG pin)
• Current limiter circuit (Supports 0.25 V (typical) reference voltage sensing based high-precision detection)
• Undervoltage 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 outputs
• Supports thermistor based thermal protection of the output transistors
