VARIABLE SPEED SINGLE-PHASE BLDC MOTOR CONTROLLER
DESCRIPTION
The ZXBM1004 is a single-phase, DC brushless motor pre-driver with PWM
variable speed control suitable for fan and blower motors. The controller is
intended for applications where the fan or blower speed is controlled by an
external PWM signal, thermistor or DC voltage.
FEATURES
Compliant with external PWM speed control
Compliant with thermistor control
Minimum speed setting
Low noise
Auto restart
Built in hall amplifier
Speed pulse (FG) and lock rotor (RD) outputs
Up to 18V input voltage (60V with external regulator)
QSOP16 package
Associated application notes:-
AN41 - Thermistor control
AN42 - External PWM control
AN43 - Interfacing to the motor windings
QSOP16
APPLICATIONS
Mainframe and personal computer fans and blowers
Instrumentation fans
Central heating blowers
Automotive climate control

VCC - Applied Voltage
This is the device internal circuitry supply voltage. For
5V to 12V fans this can be supplied directly from the
Fan Motor supply. For fans likely to run in excess of the
18V maximum rating for the device this will be
supplied from an external regulator such as a Zener
diode.

Applications Information
The ZXBM1004 is primarily controlled by a voltage on
the SPD pin. A voltage of 1V represents a 100% PWM at
the Phase Outputs and in turn represents full speed. 3V
on the SPD pin conversely represents 0% PWM. The
motor can therefore be controlled simply by applying a
control voltage onto the SPD pin with the minimal use
of external components.
This voltage control method easily lends itself to
control by other signal types. For example if a
thermistor is applied to the SPD pin a varying voltage
can be generated at the SPD pin as the resistance of the
thermistor varies with temperature.
A common form of control of fans is by a PWM signal
derived from a central processor or controller. This
signal can be converted into a voltage and that voltage
adjusted as neccesary to compensate for motor none
linearity, inclusion of the Minimum speed feature etc.
Full applications details and further examples of how
to control the ZXBM1004 are available in the
Applications Notes AN41, AN42 and AN43.
