8 Detailed Description

8.1 Overview

The TLV170x-Q1 comparator features rail-to-rail input and output on supply voltages as high as 36 V. The rail-to-rail input stage enables detection of signals close to the supply and ground. The open-collector configuration allows the device to be used in wired-OR configurations, such as a window comparator. A low supply current of 55 μA per channel with small, space-saving packages, makes these comparators versatile for use in a wide range of applications, from portable to industrial.

8.3 Feature Description

8.3.1 Comparator Inputs

The TLV170x-Q1 device is a rail-to-rail input comparator, with an input common-mode range that includes the supply rails. The TLV170x-Q1 device is designed to prevent phase inversion when the input pins exceed the supply voltage. Figure 18 shows the TLV170x-Q1 device response when input voltages exceed the supply, resulting in no phase inversion.

8.4 Device Functional Modes

8.4.1 Setting Reference Voltage

Using a stable reference is important when setting the transition point for the TLV170x-Q1 device. The REF3333, as shown in Figure 19, provides a 3.3-V reference voltage with low drift and only 3.9 μA of quiescent current.
