Single-Phase Full-Wave Motor Driver
for Fan Motor
DESCRIPTION
EUM6179 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
www.DataShefeut4nUc.tcioomns 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
incur coil overheat/burning. To prevent this, lock
detection circuit can shut down the driver for 5 seconds
after motor lockup. Then automatic restart circuit will
try to power up the driver for 500ms every 5 seconds.
For different application, fan tachometer circuit has FG
output for EUM6179 and FG/2 output for EUM6179A.
