Overview
NEW PRODUCT ZXBM2004 TWO PHASE VARIABLE SPEED MOTOR CONTROL PRE-DRIVER Description Pin Assignments The ZXBM2004 is a 2-phase, Brushless Direct Current (BLDC) motor control pre-driver with variable PWM speed control suitable for fan and blower motors.
For system flexibility, motor speed can be controlled by changing SPD pin voltage which can be either from Thermistor network, external voltage or PWM signal.
To help protect the motor coil, the ZXBM2004 provides Rotor Lock Protection which shuts down the output drive if rotor lock is detected.
The device automatically re-starts when the rotor lock is removed.
A Tachometer output is provided by open-drain Frequency Generator (FG) Pin which allows external interface to monitor motor rotation or speed.
The FG output is the magnetic change frequency.
