HIGH = Output V1 OFF LOW = Output V1 ON VIN_GOOD/H (Input OK): Active High signal asserted when the input voltage rises above the min input voltage specified. This signal is internally pulled up through 4.7 K ohms to the 3.3 V housekeeping voltage. POK/H (Output OK): Active High signal asserted when the output is within regulation. This signal is internally pulled up through 1.0 K ohms to the 3.3 V housekeeping voltage. TACH_1: This open collector signal generates two pulses per each fan revolution. This signal is eternally pulled up to the housekeeping voltage. PS_KILL: This signal will cause the output to shut down when drive high (> 24 V) or left floating. The PS_KILL will cause the output to latch off and requires recycle of PS_ON or DC input to reset.
