For air-conditioner fan motor

3-Phase Brushless Fan Motor

Controller

BD62012FS

 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 BD62011FS and BD62014FS. 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°

intervals

Rotational direction switch

FG signal output with pulse number switch (4 or 12)

VREG output (5V/30mA)

Protection circuits provided: OCP, TSD, UVLO, MLP

and the external fault input (FIB)

 Applications

Air conditioners; air cleaners; water pumps;

dishwashers; washing machines

General OA equipment

 Key Specifications
