GENERAL DESCRIPTION
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.
