General Description
The AAT1011 is a 3-channel power supply
supervisor with 8KV ESD protection. 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.
Remote function from external signal, i.e., On/Off
Control ( ONCTL ), is also implemented.
Over voltage fault protection and under voltage
fault protection can be directly triggered without
external voltage divider.
With a minimum number of external components,
the AAT1011 offers a simple and cost effective
solution. Meanwhile, it can greatly reduce the
PCB board space for power supply system.
