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 VCC 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
