3-CHANNEL POWER SUPPLY SUPERVISOR
FEATURES
3-Channel Power Supply Supervisor Over Voltage Protection 3.3V, Under Voltage Protection 3.3V, Fault Protection Output with Open Drain Output Open Drain Power Good Output Power Good Delay ONCTL Turn Delay
GENERAL DESCRIPTION
AAT1014 3-channel power supply supervisor. provides Over Voltage Protection (OVP), Under Voltage Protection (UVP), Power Good Indicator monitor control output switching power supply system. Over voltage fault protection under voltage fault protection directly triggered without external voltage divider. AAT1014 could also greatly reduce printed circuit board space power supply system. Furthermore, remote function from external signal, i.e., On/Off Control ONCTL also implemented. versatile AAT1014 comes compact PDIP-8 package with optimized external parts offer users simple effective solutions.
ONCTL Signal De-bounce Noise De-bounce Time Latch Function Controlled ONCTL Protection Input.

(Fault Protection Output)
NORMAL="LOW", FAULT="HIGH" indicates fault condition either Over Voltage Under Voltage. When fault state occurs, latches high combines with output.
(Over Voltage Protection Under Voltage Protection)
monitors 3.3V, pin, while monitors 3.3V levels determined internal voltage dividers. typical values 3.9V, 6.1V, 13.4V 2.69V, 4.3V UVP, respectively. ONCTL (On/Off Control) On/Off Control used reset latched state externally control switching power supply system with de-bounce time. AAT1014 offers delay time after de-bounce trigger when ONCTL switches from high.
(Power Good Output)
NORMAL="HIGH", FAULT="LOW". Power Good signal will issued with delay after 3.3V, ready. Power Good Output should before output voltage regulation turn-off.
