LB11696VGEVB

LB11696VGEVB is a evaluation board for LB11696V direct PWM drive pre-driver IC. It is a 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.

• Three phase bipolar drive
• Direct PWM drive (controlled either by control voltage or PWM variable duty pulse input)
• Built in forward/reverse switching circuit and built in input amplifier
• Start/stop mode switching circuit (stop mode power saving function)
• 5V regulator output (VERG pin)
• Current limiter circuit (Supports 0.25V 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
• Four types of Hall signal pulse output
• Supports thermistor based thermal protection of the output transistors
