EUM6189A 700mA PWM Fan Motor Driver DESCRIPTION EUM6189A is designed specifically for electronic commutation of single coil brushless DC motor applications. It is intended to be used as an interface between a HALL IC and a single coil motor. The functions built in EUM6189A are soft switched drive mode, PWM speed control mode, fan tachometer, lock detection, automatic restart and thermal shut-down. Soft switched drive mode makes the output signal gentle when the amplitude of HALL signal is small. Oppositely, it makes the output signal steep when the amplitude of HALL signal is big. PWM speed control mode makes EUM6189A possible to change motor rotation speed by switching upper side power device.
