EUM6179/6179A

Single-Phase Full-Wave Motor Driver

for Fan Motor

FEATURES

DESCRIPTION

Low Voltage 2.2V~6V

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

functions built in EUM6179 are soft switched drive

mode, fan tachometer, lock detection, automatic restart,

thermal shut-down and Hall Bias.

Single-Phase Full-Wave driver System

Soft switched drive

Lock detection, Automatic restart

Tachometer Output

FG output for EUM6179,

FG/2 output for EUM6179A

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.

Thermal Shutdown Protection

FG Output

RoHS Compliant and 100% Lead (Pb)-Free

APPLICATIONS

NB FAN Motor

For different application, fan tachometer circuit has FG

output for EUM6179 and FG/2 output for EUM6179A.
