LB11873中文资料LB11873: Three-Phase Brushless Motor Driver for Polygonal Mirror Motors数据手册ONSEMI规格书

描述 Description

The LB11873 is a 3-phase brushless motor driver developed for driving the polygonal mirror motor used in plain-paper copiers and similar products. This IC can implement the circuits required for polygonal mirror motor drive (speed control and driver circuits) in a single chip. The LB11873 implements low-noise/low-vibration PWM drive by changing the current at phase switching gradually to reduce motor noise.

特性 Features

Three-phase bipolar drive (quiet direct PWM)
PLL speed control circuit
Hall sensor FG support
Dedicated external clock
Brake mode switching circuit (free running and reverse braking)
Phase lock detection output (with masking function)
Built-in current limiter, constraint protection, undervoltage protection, thermal protection, and CLK line disconnection protection circuits
Input pins support 3V system microcontrollers
