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.
