LB11693H中文资料LB11693H: Direct PWM Drive 3-Phase Brushless Motor Driver for Driving 24V Fan Motors数据手册ONSEMI规格书

描述 Description

The LB11693H 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 24V fan motors.

特性 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 circuit
