FPO (Fault Protection Output)
NORMAL=“LOW”, FAULT=“HIGH”
FPO indicates the fault condition of either Over
Voltage or Under Voltage. When a fault state
occurs, the FPO would be latched high and
combined with a low PGO output.
PGO (Power Good Output)
AAT1015
OVP and UVP (Over Voltage Protection and
Under Voltage Protection)
OVP monitors 3.3V, 5V, and 12V via V_CC pin,
while UVP monitors 3.3V and 5V. OVP and
UVP levels are determined by internal voltage
dividers. The typical values are 3.9V, 6.1V,
13.8V for OVP and 2.2V, 3.5V for UVP,
respectively.
NORMAL=“HIGH”, FAULT=“LOW”.
A Power Good signal will be issued with 300 ms
delay after 3.3V, 5V, 12V and PGI are ready.
Power Good Output should be low before the
output voltage is out of regulation at turn-off.
ONCTL (On/Off Control)
On/Off Control is used to reset the latched state of
FPO and to externally control the switching
power supply system with a 38 ms de-bounce time.
AAT1015 offers 2.3 ms delay time after de-bounce
to trigger FPO when ONCTL switches from
low to high
