LB11697V: Direct PWM Drive Brushless Motor Predriver

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. Furthermore, the LB11697V provides a full complement of protection circuits allowing it to easily implement high-reliability drive circuits. Note that the LB11697V is a modified version of the LB11696V in which the output logic has been optimized for 12 V system motors. This allows the number of external components to be reduced in application circuits.

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
