3-CHANNEL POWER SUPPLY SUPERVISOR
FEATURES
3-Channel Power Supply Supervisor Over Voltage Protection 3.3V, Output Under Voltage Protection 3.3V, Output with Enable Delay Fault Protection Output with Open Drain Output Open Drain Power Good Output Power Good Delay ONCTL Turn Delay
GENERAL DESCRIPTION
AAT1015 3-channel switching power supply supervisor that provides Over Voltage Protection (OVP), Under Voltage Protection (UVP), Power Good Indicator monitor control output switching power supply system. addition implemented remote function from external signal, i.e., On/Off Control ONCTL over voltage fault protection under voltage fault protection also directly triggered without external voltage divider. AAT1015 also greatly reduce board space power supply system. With minimal number external components, AAT1015 offers simple cost effective solution.
ONCTL Signal De-Bounce De-Bounce Latch Function Controlled ONCTL Protection Input.

(Fault Protection Output) (Over Voltage Protection Under Voltage Protection)
NORMAL="LOW", FAULT="HIGH" indicates fault condition either Over Voltage Under Voltage. When fault state occurs, would latched high combined with output.
(Power Good Output)
monitors 3.3V, pin, while monitors 3.3V levels determined internal voltage dividers. typical values 3.9V, 6.1V, 13.8V 2.2V, 3.5V UVP, respectively. ONCTL (On/Off Control) On/Off Control used reset latched state externally control switching power supply system with de-bounce time. AAT1015 offers delay time after de-bounce trigger when ONCTL switches from high
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.
