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.
