TPV8348

Nano Power Supervisory Circuits with Programmable Reset Delay

Overview

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 30 μs 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.
