LB11697V Direct PWM Drive Brushless Motor Predriver

LB11697V Monolithic Digital IC Direct PWM Drive Brushless Motor Predriver IC http://onsemi.com Overview The LB11697V 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. Furtherm.

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 out.
