L6230 DMOS driver for three-phase brushless DC motor
Cristiana Scaramel
Introduction
Modern motion control applications need more flexibility that can be only addressed with
specialized ICs products. The L6230 is a DMOS fully integrated three-phase BLDC motor
driver optimized for field oriented control (FOC) application thanks to the independent
current senses. The device integrates six DMOS power transistors with CMOS and bipolar
circuits on the same chip including overcurrent protection for safe operation and flexibility.
An uncommitted comparator with open-drain output for optional function is available.
