The A1444 and A1445 employ a soft-switching algorithm to reduce audible switching noise and EMI interference.

Allegro MicroSystems Europe has released the A1444 and A1445 low-voltage, full-bridge brushless DC motor driver ICs with integrated Hall commutation and internal PWM (pulse-width-modulation) speed control Designed for applications that require rotor speed control and fast rotor start/stop cycles, the new devices are based on a high-density CMOS semiconductor process that allows the integration of a Hall element, an H-bridge output driver and PWM speed control logic into a monolithic IC
