Sine-wave PWM drive system and rotor position detection method by 1-Hall-sensor
1-Hall-Sensor Driver IC for 3-phase Brushless Motor
FEATURES
 Supply voltage range: 6.0 V to 26.4 V
 Built-in 5-V regulator
 3-phase full-wave sine-wave PWM drive by 1-Hall-sensor
 VSP pin linear input
 Drive phase shift control
 Rotation direction selectable (Forward/Reverse)
 FG pulse divide selectable
 Stand-by mode
 Various protection functions: under voltage lock out (UVLO),
over voltage lock out (OVLO), thermal protection, over load
protection, and over current protection
 24-pin plastic quad flat non-lead package
(QFN type, size: 4 mm  4 mm)
DESCRIPTION
AN44140A 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.
