Preliminary Specification  
aMC8520  
SINGLE PHASE VARIABLE SPEED  
ADVANCED FAN CONTROLLER  
Product Description  
The aMC8520 is a full featured single phase brushless DC  
motor controller that contains all the required functions for an  
economical closed loop motor control solution that fulfills the  
balanced technology extended (BTX) requirements allowing  
a significant reduction of acoustic noise generation. Unique  
features of this device are a pulse width modulation (PWM)  
speed control input that is compatible with industry standard  
digital temperature monitors, thermistor input with adjustable  
gain and minimum temperature response threshold for  
temperature monitoring, programmable high and low  
temperature maximum RPM, programmable minimum RPM,  
current output error amplifier for easy control loop  
compensation. Additional features include a latching PWM  
for enhanced noise immunity, integrated fault timer with auto  
start retry, adaptive motor start timer to insure start up,  
combined frequency generator / rotor lock output, Hall  
amplifier with propriety noise immunity circuitry for proper  
drive sequencing, compatibility with differential non-buffered  
and buffered sensors, pinned out reference for Hall and  
circuit bias, fixed non-overlapping commutation delay for  
reduced power supply current spiking, two 40 V open drain  
top drivers, two 100 mA complementary MOSFET bottom  
drivers, programmable cycle-by-cycle current limiting, under  
voltage lockout and thermal shutdown protection, and an  
internal shunt regulator for use with higher voltage motors.
