EUM6179/6179A Single-Phase Full-Wave Motor Driver for Fan Motor
DESCRIPTION
EUM6179 is designed specifically for electronic mutation 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 EUM6179 are soft switched drive .. mode, fan tachometer, lock detection, automatic restart, thermal shut-down and Hall Bias. 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. If the motor is stalled by external force or obstacles, overdrive current may...
