PIN CONFIGURATION TOP VIEW PGI 1 8 PGO GND 2 7 Vcc FPO 3 6 V5 ONCTL 4 5 V33 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.

AAT1015 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 would be latched high and combined with a low PGO output. PGO (Power Good Output) NORMAL=“HIGH”, FAULT=“LOW”. A 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, 13.8V for OVP and 2.2V, 3.5V 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 a 38 ms de-bounce time. AAT1015 offers 2.3 ms delay time after de-bounce to trigger FPO when ONCTL switches from low to high – 台灣類比科技股份有限公司 – – Advanced Analog Technology, Inc. – Page 2 of 11 V 1.0 Advanced Analog Technology, Inc.
