A1442 Datasheet Low Voltage Full Bridge Brushless DC Motor Driver

Manufacturer: Allegro MicroSystems

Overview: A1442 Low Voltage Full Bridge Brushless DC Motor Driver with Hall mutation and Soft Switching, and Reverse Battery, Short Circuit, and Thermal Shutdown.

General 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.

Key Features

  • Low voltage operation.
  • Reverse voltage protection on VDD and S¯¯L¯¯E¯¯E¯¯P pins.
  • Output short circuit and thermal shutdown protections.
  • Soft switching algorithm to reduce audible switching noise and EMI interference.
  • Unidirectional working mode provides motor rotation in one direction.
  • Hall chopper stabilization technique for precise signal response over operating range.
  • Sleep mode pin allowing external logic signal enable/ disable to reduce average power cons.
