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 ...
