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