LB11693JH ^{Monolithic Digital IC}
24V Fan Motor Driver IC
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
