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. 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
