Overview

A1441 Low-Voltage Full-Bridge Brushless DC Motor Driver with Hall Element Commutation Features and Benefits ▪ Single-chip solution for high reliability ▪ Chopper stabilization technique for precise signal response over operating range ▪ 2.
0 to 4.
0 V operation ▪ Sleep mode pin allowing external logic signal enable/ disable to reduce average power consumption ▪ Restart feature ▪ Small package size Description 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 proce...
