A1441 - Low-Voltage Full-Bridge Brushless DC Motor Driver

The A1441 is a full-bridge motor driver designed to drive low-voltage bipolar brushless dc motors.

Commutation of the motor is achieved by use of a single Hall element sensor to detect the position of an alternating-pole ring magnet.

A high density merged Bipolar-CMOS semiconductor process allows th
