Low-Voltage Full-Bridge Brushless DC Motor Driver
with Hall Element Commutation
A1441
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 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.
