BD62012AFS Datasheet, PDF (1/24 Pages) Rohm – 3-Phase Brushless Fan Motor Controller

For air-conditioner fan motor
3-Phase Brushless Fan Motor
Controller
BD62012AFS
 General Description
This controller synthesizes the optimal driving signal
from hall sensor signals, and outputs the synthesized
signal to control the external level shifter and power
transistor. The replacement is also easy because of its
pin compatibility with BD62011AFS and BD62014AFS.
This controller provides optimum motor drive for a wide
variety of applications, and enables motor unit
standardization.
 Features
 150° commutation logic
 PWM control (Upper arm switching)
 Phase control supported from 0° to +30° at 1°
