5 Detailed Description

5.1 Overview

The TLV181x-EP and TLV182x-EP devices are micro-power comparators with push-pull and open-drain output

options. Operating down to –55°C while only consuming only 5µA per channel, the TLV181x-EP and TLV182x-

EP are well suited for power conscious systems and supply monitoring applications. An internal power-on reset

circuit ensures that the output remains in a known state during power-up and power-down.
