Logic Control
PS_ON/L:
(Power supply enable)
The power supply output will be enabled when this signal is pulled low (< 0.8 V).
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.
Digital Control:
PMBus - I2C compliant
