Additional Details

The RN5RG35AA voltage detector IC compares the input voltage to an internal reference voltage. When the input voltage drops below the detection voltage, the output signal is asserted. The datasheet specifies the delay time before the output is asserted after the voltage falls below the threshold. Also specified are the hysteresis of the voltage detection and the release voltage. It is important to refer to the manufacturer's datasheet for precise specifications, including the output voltage level and the maximum allowable input voltage. It may also provide timing diagrams for the output response.
