ZXBM2 series - Two-phase variable speed brushless fan motor controllers

The ZXMB200x are a series of two-phase, DC brushless motor pre-drivers with variable speed control suitable for fan and blower motors.

The analog format speed control allows 0 - 100% control of the PWM drive outputs, allowing suitable speed control for all motor applications. If required, thermal control can be achieved by simply adding an NTC thermistor. It is available in several variants featuring rotor lock and speed outputs.
