Built in 18V Full-wave Fan Driver  
PWM Control Mode  
EUM6270 is a PWM fan motor driver for single coil  
brushless DC motor. With its high efficient direct  
PWM control mode, EUM6270 controls the speed of  
brushless DC motor. It builds in an interface between a  
HALL IC and a single coil motor. EUM6270 is  
suitable for variable speed control motor for personal  
computer’s power supply radiation fans and CPU  
coolers.  
The EUM6270 functions include PWM control mode,  
minimum speed mode, fan tachometer, soft switching,  
lock protection, auto restart, current limit and Hall  
Bias.  
PWM mode controls internal power devices in low  
noise and low vibration fashion. Minimum speed mode  
makes the lowest speed of motor settable. If the motor  
is stalled by external force or obstacles, overdrive  
current may incur coil overheat and burning. To  
prevent motor from overheating, the lock protection  
circuit will shut down the internal power devices for a  
few seconds after motor is locked up. Then auto restart  
circuit resumes to power up. The protection and power  
up time are settable by external capacitor. When the  
voltage drop between VCC and VM is higher than  
0.48V (Typ.), the EUM6270 outputs will be turned off  
by current limit function. EUM6270 has motor rotation  
speed feedback (FG) output and Hall sensor bias  
output.
