TLV1811LDBVR

Comparators Overview

The TLV1811LDBVR is a single-channel micro-power high-voltage analog comparator from the Texas Instruments TLV181x family. It features rail-to-rail inputs and a push-pull output stage, operating within a wide supply voltage range of 2.4V to 40V. The device incorporates an internal Power-On Reset (POR) circuit to ensure known startup states. Key electrical characteristics include a typical propagation delay of 420ns, low quiescent current of 5µA per channel, and input offset voltage of 500µV. It is housed in a SOT-23-5 package.

Comparators Feature Summary

• Rail-to-rail input capability extending beyond supply rails for flexible signal interfacing
• Push-pull output stage capable of sourcing and sinking milliamps of current
• Integrated Power-On Reset (POR) function for reliable system initialization
• Micro-power operation with low quiescent current consumption

Comparators Applications

• Appliances
• Factory automation and control
• Motor drives
• Infotainment and cluster systems

Comparators Procurement Notes

Verify the specific 'L' suffix indicates the alternate pinout configuration compatible with legacy devices like LMC72x1/TLV72x1 families. Confirm the DBV package designation corresponds to the SOT-23-5 form factor. Ensure design requirements align with the push-pull output topology, as opposed to the open-drain variant found in the TLV182x series.

Comparators Selection Notes

Select this component when a single comparator with push-pull drive capability is required for high-voltage applications up to 40V. It is suitable for designs needing rail-to-rail input compatibility and low power consumption. Consider the alternate pinout if replacing older LMC or TLV72 parts. Verify thermal management needs based on the SOT-23-5 package thermal resistance metrics.

Comparators Part Context

This part belongs to the TLV181x and TLV182x family of 40V rail-to-rail input comparators. The TLV181x sub-series specifically provides push-pull outputs, distinguishing it from the TLV182x open-drain options. The 'L' designation denotes an alternative pinout arrangement designed to facilitate direct upgrades from previous generation comparator families without PCB redesign.

Comparators Replacement Considerations

Public confirmed substitute part numbers: TLV1811DBVR (Standard Pinout), TLV1821DBVR (Open-Drain Output). Note that these substitutes differ in pinout configuration or output topology compared to the TLV1811LDBVR.
