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 the integration of the Hall element on the same IC as the motor control circuitry, providing a single-chip solution for enhanced reliability. All necessary circuitry is incorporated within the device package, eliminating the need for any external support components.
A micropower sleep mode can be enabled by an external signal, to reduce current consumption for battery management in portable electronic devices. In addition, the device offers an active function for motor braking.
The A1441 is optimized for vibration motor applications such as cellular phones, pagers, electronic toothbrushes, and hand-held video game controllers. These devices also drive low power fan motors designed with cogging plates.
The small package outline and low profile make this device ideally suited for use in applications where printed circuit board area and component headroom are at a premium. It is available in a lead (Pb) free (leadframe plating 100% matte tin) 6-pin MLP microleadframe package for surface mount, with exposed pad for enhanced thermal dissipation.
