Overview
The LB11693 reduces motor noise by imparting a slope to the output current when switching the phase to which power is applied. This motor driver includes an automatic recovery constraint protection circuit and is optimal for driving 24 V fan motors.

Functions and Features
• Soft phase switching + direct PWM drive
• PWM control based on both a DC voltage input (the CTL voltage) and a pulse input
• Provides a 5 V regulator output
• One Hall-effect sensor FG output
• Integrating amplifier
• Automatic recovery constraint protection circuit (on/off = 1/14), RD output
• Current limiter circuit
• LVSD circuit
• Thermal protection circuitt
