KA44143A Overview
Description
KA44143A 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 power consumption.
Key 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
