The A1442 is a full-bridge motor driver designed to drive low-voltage, brushless dc motors. Commutation of the motor is achieved by use of a single Hall element sensor to detect the rotational position of an alternating-pole ring magnet. A highdensity CMOS semiconductor process allows the integration of all the necessary electronics. This includes the Hall element sensor, the motor control circuitry, and the full output bridge. Low-voltage design techniques have been employed to achieve full device functionality down to low VDD values. This fully integrated single chip solution provides enhanced reliability (including reverse battery protection and output short circuit protection) and eliminates the need for any external support components. |
