A1442 - Low Voltage Full Bridge Brushless DC Motor Driver

The A1442 is a full-bridge motor driver designed to drive lowvoltage, brushless DC motors.

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

A high-density CMOS semiconductor process allows the integration of al
