ZXBM2004 Overview
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...
