6.1 Overview

The TPS3711 combines a comparator and a precision reference for undervoltage detection. The TPS3711 features a wide supply voltage range (1.8 V to 36 V) and a high-accuracy threshold voltage of 400 mV (0.75% overtemperature) with built-in hysteresis. The output is rated to 25 V and can sink up to 10 mA.

Set the input pin (SENSE) to monitor any voltage above 0.4 V by using an external resistor divider network. SENSE has very low input leakage current, allowing the use of a large resistor divider without sacrificing system accuracy. The relationship between the input and the output is shown in Table 6-1. Broad voltage thresholds are supported that enable the device to be used in a wide array of applications.
