ZXBM1021  
SINGLE PHASE VARIABLE SPEED  
MOTOR CONTROL PRE-DRIVER  
Description  
Pin Assignments  
The ZXBM1021 is a high performance, low noise, single-phase,  
Direct Current Brushless (BLDC) motor pre-driver with variable  
PWM speed control and current control suitable for fan and blower  
motors.  
(Top View)  
For system flexibility the motor speed can be controlled by either an  
external PWM control signal or by a DC voltage signal from an  
external control voltage or from a Thermistor network.  
To prevent motor inrush current the device has a soft start feature.  
To help protect the motor coil, the ZXBM1021 provides rotor lock  
protection which shuts down the output drive if rotor lock is  
detected. The device automatically re-starts with soft-start when the  
rotor lock is removed. The ZXBM1021 monitors the motor current  
to provide a programmable over current limit.  
A Tachometer output is provided by the open collector output  
Frequency Generator (FG) pin which allows external interface to  
monitor motor rotation or speed. The FG output is the magnetic  
change frequency.  
U-QFN4040-20  
The ZXBM1021 is available in space saving and low profile  
U-QFN4040-20 package.
