Preliminary EUM6867 PWM Pre Driver for DC Fan Motor DESCRIPTION EUM6867 is a pre driver for single coil brushless DC motor, specially designed for 12V power supply application. With an external PWM input signal, EUM6867 can control the speed of DC motor. It is an interface between a HALL IC and a single coil motor. The functions built in EUM6867 include soft start mode, 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. With soft start function. EUM6867 can drive motor from slow speed to fast speed in a settable time by setting the external capacitor between S-S and 5VREG.
