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
