EUM6167
Single-Phase Full-Wave Pre Driver
for Fan Motor
DESCRIPTION
EUM6167 is a pre driver for single coil brushless DC
motor. With an external PWM input signal, EUM6167
can control the speed of DC motor. It is an interface
between a HALL IC and a single coil motor. The
functions built in EUM6167 include PWM control
mode, minimum speed mode, soft-switching time, fan
tachometer, lock protection, auto restart, Hall Bias and
current limiter. PWM mode controls the external
PMOS-NMOS FET in low noise and low vibration.
Minimum speed mode makes the lowest speed of
motor settable. Soft-switching time can cut the
ineffective current when phase change is not set. If the
motor is stalled by external force or obstacles,
overdrive current may incur coil overheat/burning. To
prevent this, lock protection circuit can shut down the
external power devices for a few seconds after motor
lockup. Then auto restart circuit will try to power up
these devices. The protection and power up time are
settable by external capacitor. EUM6167 has FG
output and RD output.
