9.1 Overview

The TPS3840-Q1 is a family of wide VDD and nano-quiescent current voltage detectors with fixed threshold voltage. TPS3840-Q1 features include programable reset time delay using external capacitor, active-low manual reset, 1% typical monitor threshold accuracy with hysteresis and glitch immunity.

Fixed negative threshold voltages (VIT-) can be factory set from 1.6 V to 4.9 V (see Table 3 for available options). TPS3840-Q1 is available in SOT-23 5 pin industry standard package.
