Overview

The LB11693JH is a three-phase brushless motor driver IC that uses a direct PWM drive technique to achieve highly efficient drive. It is optimal for driving fuel pump motors and other miniature motors.

Functions

• Soft phase switching + Direct PWM drive

• PWM control based on both a DC voltage input (the CTL voltage) and a pulse input

• Provides a 5V regulator output

• One Hall-effect sensor FG output

• Built-in integrating amplifier

• Automatic recovery constraint protection circuit (on/off = 1/14), RD output

• Built-in current limiter circuit

• Built-in LVSD circuit

• Built-in thermal protection circuit
