The new A1441 from Allegro MicroSystems Europe is a full-bridge motor driver integrated circuit designed to drive single-phase, low-voltage bipolar brushless DC motors.
Commutation of the motor is achieved by the use of a single Hall-effect sensing element that detects the position of an alternating pole ring magnet. The Hall element is integrated on the same IC as the motor control circuitry, providing a single-chip solution for high reliability.
The A1441 is optimised for use with the vibration motors - including the thinner coin-type motor designs - that are typically used in portable electronic devices such as mobile phones, pagers and handheld video game controllers. It is also suited to use in gaming machines, where brushless motors are increasingly being used for higher reliability, as well as for driving low-end fan motors that do not require currents above 150 mA.
All necessary circuitry is integrated and no external devices are required - although a bypass capacitor is recommended to lower switching transients and therefore reduced radiated emissions.
The switchpoints of the device are chopper-stabilised for precision, and the device will operate down to 2,0 V. The full H-bridge output provides higher torque at start-up. An active braking function and 'sleep' mode can be enabled by an external signal.
The device is available in a low-profile 2 x 2 x 0,5 mm MLP package with 100% tin plating (EL package).
