For air-conditioner fan motor
3-Phase Brushless Fan Motor
Controller
BD62011AFS
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 BD62012AFS and BD62014AFS.
This controller provides optimum motor drive for a wide
variety of applications, and enables motor unit
standardization.
Features
180° sinusoidal commutation logic
PWM control (Upper and lower arm switching)
Phase control supported from 0° to +40° at 1°
intervals
Rotational direction switch
FG signal output with pulse number switch (4 or 12)
VREG output (5V/30mA)
Protection circuits provided: OCP, UVLO, TSD, MLP
and the external fault input (FIB)
Applications
Air conditioners; air cleaners; water pumps;
dishwashers; washing machines
General OA equipment

Datasheet
11) Thermal shutdown (TSD) circuit
The TSD circuit operates when the junction temperature of the controller exceeds the preset temperature (175°C
nominal). At this time, the controller forces all driver outputs low. Since thermal hysteresis is provided in the TSD circuit,
the chip returns to normal operation when the junction temperature falls below the preset temperature (150°C nominal).
The TSD circuit is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or
guarantee its operation in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is activated,
and do not use the IC in an environment where activation of the circuit is assumed.
12) Motor lock protection (MLP) circuit
When the controller detects the motor locking during fixed time of 4 seconds nominal when each edge of the hall signal
doesn't input either, the controller forces all driver outputs low under a fixed time 20 seconds nominal, and self-returns to
normal operation. This circuit is enabled if the voltage force to VSP is over the duty minimum voltage VSPMIN, and note
that the motor cannot start up when the controller doesn’t detect the motor rotation by the minimum duty control.
13) External fault signal input pin (FIB pin, low active)
The FIB pin can force all controller driver outputs low at any time. The FIB pin is pulled up to VREG internally by a 100
kresistor. Therefore, an open drain output can be connected directly. It is recommended to pull up FIB pin to VREG
voltage when this function is not used or malfunctioning because of the noise.
14) Hall signal wrong input detection
Hall element abnormalities may cause incorrect inputs that vary from the normal logic. When all hall input signals go high
or low, the hall signal wrong input detection circuit forces all driver outputs low. And when the controller detects the
abnormal hall signals continuously for four times or more motor rotation, the controller forces all driver outputs low and
latches the state. It is released if the duty control voltage VSP is forced to ground level once.
15) Internal voltage regulator
The internal voltage regulator VREG is output for the bias of the hall
element and the phase control setting. However, when using the VREG
function, be aware of the IOMAX value. If a capacitor is connected to the
ground in order to stabilize output, a value of 1 µF or more should be used.
In this case, be sure to confirm that there is no oscillation in the output.
