A1442 Description
The A1442 is a full-bridge motor driver designed to drive lowvoltage, brushless DC motors. mutation 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 all the necessary electronics.
