AAT1011 Advanced Analog Technology, Inc., AAT1011 Datasheet - Page 2

• Manufacturer Part Number: AAT1011
• Description: 3-channel Pc Power Supply Supervisor For 3.3v, 5v And 12v
• Manufacturer: Advanced Analog Technology, Inc.

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 latched high and combined with a
low PGO output.
PGO (Power Good Output)
NORMAL=“HIGH”, FAULT=“LOW”.
The 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.

OVP and UVP
OVP monitors 3.3V, 5V, and 12V (via Vcc pin)
UVP monitors 3.3V and 5V.
levels are determined by internal voltage dividers.
The typical values are 3.9V, 6.1V, 13.8V for OVP
and 2.83V, 4.3V for UVP, respectively.
On/Off Control is used to reset the latched state of
power supply system with a 49 ms de-bounce time.
AAT1011 offers 2.3 ms delay time after de-bounce
to trigger FPO when ONCTL switches from
low to high
