| Advanced Analog Technology, Inc. AAT1014 Details are subject to change without notice 3-CHANNEL PC POWER SUPPLY SUPERVISOR FEATURES 3-Channel PC Power Supply Supervisor Over Voltage Protection for 3.3V, 5V, and 12V Under Voltage Protection for 3.3V, 5V Fault Protection Output with Open Drain Output Open Drain Power Good Output 300 ms Power Good Delay 2.3 ms ONCTL to FPO Turn Off Delay 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. 38 ms ONCTL Signal De-bounce 73 s Noise De-bounce Time Latch Function Controlled by ONCTL and Protection Input. PIN CONFIGURATION VCC FPO ONCTL - - xAEWAniN/|-1/2q - Advanced Analog Technology, Inc. - Page 1 of 11 V 1.0 Advanced Analog Technology, Inc. AAT1014 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. 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. 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. - - xAEWAniN/|-1/2q - Advanced Analog Technology, Inc. - Page 2 of 11 V 1.0 Advanced Analog Technology, Inc.
