AN44143A 3-phase Brushless Motor Driver

* AN44143A is a driver IC for 3-phase brushless motor optimized for fan motors. By employing the rotor position detector and sine wave PWM drive by 1-Hall-sensor, this IC achieves component reduction and miniaturization of motor set as well as motor drive at low noise, low vibration and low powe.

AN44143A Features

* Supply voltage range: 4.5 V ~ 26.4 V

* Built-in 5-V regulator

* 3-phase full-wave sine-wave PWM drive by 1-Hall-sensor

* Selectable Input Mode: Either linear voltage input or PWM input through VSP pin

* Selectable the start frequency through SWSF pin

* Conduction angle auto
