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. 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.
EUM6189A has FG output.
