AMC8510

www.DataSheet4U.com Preliminary Specification aMC8510 SINGLE PHASE VARIABLE SPEED FAN MOTOR CONTROLLER Product Description The aMC8510 is a full featured monolithic brushless DC motor controller containing all the required driver functions to implement fan speed control. This device features a selectable slope pulse width modulator (PWM) for efficient speed control that is compatible with analog and digital control signals, programmable minimum speed setting, selectable automatic fan power down mode for power sensitive applications, latching PWM for enhanced noise immunity, integrated fault timer with auto start retry, adaptive motor kick 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, op amp and pinned out reference for thermal sensor voltage scaling, fixed non-overlapping commutation delay for reduced power supply current spiking, two 40 V open drain top drive outputs, two 100 mA complementary bottom drive outputs that are ideally suited for driving power MOSFETs, programmable cycle-by-cycle current limiting, under voltage lockout and thermal shutdown protection, and an internal shunt regulator for use with higher voltage motors.
