L99ASC03 PMBLDC sensorless 3-phase motor driver
G. Celeste; G.Maimone
Introduction
The L99ASC03 is a 3-phase BLDC driver IC. The device can drive six external MOSFETs in
BLDC drive systems and detect back EMF zero-crossing events, thus allowing sensorless
rotor position detection.
This application note is intended to provide guidance to users on specific application-related
topics.
