... Smart Multi-Voltage Detector General Description The RT9823 is an integrated smart multi voltage detector supervising two power supply voltage levels including 5V, and another voltage (such as 3.3V or 12V) , which can be set via an external resistive voltage divider. The RT9823 performs supervisory function by sending out a CTR signal whenever the monitored voltages fall below 80% of the voltage levels ...
