ZXBM2004
VARIABLE SPEED 2-PHASE BLDC MOTOR CONTROLLER
DESCRIPTION
The ZXBM2004 is a 2-phase, DC brushless motor pre-driver with PWM
variable speed control suitable for fan and blower motors. The controller is
intended for applications where the fan or blower speed is controlled by an
external PWM signal, thermistor or DC voltage.
FEATURES
