EUM6189A

700mA PWM Fan Motor Driver

DESCRIPTION

FEATURES

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.

Single-Phase Full-Wave driver System

Soft switched drive

PWM speed control mode

Lock detection, Automatic restart

Tachometer Output

FG output

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.

Thermal Shutdown Protection

Available in MSOP-8 Package

RoHS Compliant and 100% Lead (Pb)-Free

APPLICATIONS

NB FAN Motor

EUM6189A has FG output.
