GENERAL DESCRIPTION
The AAT1015 is a 3-channel PC switching power
supply supervisor that 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.
In addition to the implemented remote function
from external signal, i.e., On/Off Control
( ONCTL ), over voltage fault protection and under
voltage fault protection can also be directly
triggered without external voltage divider.
AAT1015 also greatly reduce the PCB board
space for power supply system.
With a minimal number of external components,
the AAT1015 offers a simple and cost effective
solution.
