Low Quiescent Current Supervisory Circuits with Programmable Reset Delay


The TPV8308 is a family of supervisory circuits to monitor a voltage rail from 0.405 V to 5 V, asserting an active low/active high open-drain or push-pull RESET /RESET output when the voltage of the sense pin drops below a fixed threshold or when the manual reset pin MR is logic low. The RESET /RESET output remains low/high for the user-adjusted delay time by the external capacitor after the sense voltage returns above the fixed threshold with a hysteresis and the manual reset MR return to logic high.

The threshold voltage of the TPV8308 device can achieve 1% accuracy. The delay time can be set to 1.25 ms to 10 s by connecting the external capacitor to the CT pin. The TPV8308 family has a very low typical quiescent current of 600 nA.

The TPV8308 is available in SOT23 and DFN2x2 packages. Its operating temperature range is from -40°C to +125°C.
