Advanced Analog Technology, Inc. AAT1014 Details are subject to change without notice 3-CHANNEL PC POWER SUPPLY SUPERVISOR FEATURES www.DataSheet4U.com z 3-Channel 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.
