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
