PIN CONFIGURATION
The AAT1014 is a 3-channel PC power supply
supervisor. It provides Over Voltage Protection
(OVP), Under Voltage Protection (UVP), and
Power Good Indicator to monitor and control the
output of the switching power supply system.
Over voltage fault protection and under voltage
fault protection can be directly triggered without
any external voltage divider. AAT1014 could also
greatly reduce the printed circuit board space for
PC power supply system. Furthermore, remote
function from external signal, i.e., On/Off Control
( ONCTL ), is also implemented.
The versatile AAT1014 comes in a compact
PDIP-8 package with optimized external parts to
offer its users simple and effective solutions.

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 latches high and combines 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 (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,
13.4V for OVP and 2.69V, 4.3V for UVP,
respectively.
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 38 ms de-bounce time.
AAT1014 offers 2.3 ms delay time after de-bounce
to trigger FPO when ONCTL switches from
low to high.
