The TPV8348 is a family of supervisory circuits to monitor a voltage rail,asserting an active low or active high RESET/RESET output when the voltage of the VDD pin(Fixed version)or SENSE pin(Adjustable version)drops below the threshold or when the manual reset pin MR is logic low.The RESET/RESET output remains low or high for the duration of the delay time after the detected voltage returns above the threshold with a hysteresis or manual reset MR returns to logic high.The delay time can be set by an external capacitor.The threshold voltage of the TPV8348 device can achieve 1%accuracy.The delay time can be set to 30μs to 6.2 s by connecting the external capacitor to the CT pin.The TPV8348 family has a very low typical quiescent current of 400 nA.The TPV8348 is available in SOT23-5 and DFN1.5x1-6 packages.Its operating temperature range is from−40°C to+125°C.
