... Smart Multi-Voltage Detector General Description The RT9824 is an integrated smart multi-voltage detector supervising three power supply voltage levels including 5V, 5.4V and additional 3.3V, 12V or other voltage which can be determined by external divided resisters. The RT9824 performs supervisory function by sending out RESET and CTR signals whenever the monitored voltages fall below 80% of voltage levels ...
