AMC8510 Datasheet | Andigilog

Description The a MC8510 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 patible 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, bined frequency generator / rotor lock output, Hall amplifier with propriety noise immunity circuitry for proper drive sequencing, patibility with differential non-buffered and buffered sensors, op amp and pinned out reference for thermal sensor voltage scaling, fixed non-overlapping mutation delay for reduced power supply current spiking, two 40 V open drain top drive outputs, two 100 m A plementary 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.
