Motor control microcontroller 4.7 - 18 V, 7.5 mA | ZXBM2004

The ZXBM2004 is a 2-phase, Brushless Direct Current (BLDC) motor control pre-driver with variable PWM speed control suitable for fans, blowers and motors. For system flexibility the motor speed can be controlled by a voltage signal on SPD pin from either a Thermistor network, external control voltage or a 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. The ZXBM2004 is available in space saving low profile QFN3030-16 and QSOP16 packages.
