TLV1811QDBVRQ1

Comparators Overview

The TLV1811QDBVRQ1 is a single-channel automotive analog comparator from Texas Instruments, housed in an SOT-23-5 package. It operates within a supply voltage range of 2.4 V to 40 V and features rail-to-rail inputs with a push-pull output stage. Key electrical specifications include a quiescent current of 5 μA per channel, a typical propagation delay of 420 ns, and an input offset voltage of 500 μV. The device includes a Power-On Reset (POR) function and meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Comparators Feature Summary

• Qualified for automotive applications with AEC-Q100 Grade 1 certification
• Features rail-to-rail inputs and a push-pull output stage
• Includes internal Power-On Reset (POR) circuitry for known start-up states
• Designed for low power consumption with micro-power quiescent current

Comparators Applications

• HEV/EV and power train systems
• Infotainment and cluster displays
• Body control modules

Comparators Procurement Notes

Verify the specific ordering suffix DBVR corresponds to the SOT-23-5 package and tape-and-reel delivery format. Confirm that the Q1 suffix indicates AEC-Q100 qualification suitable for automotive environments. Ensure the component matches the standard North West pinout configuration defined in the datasheet before integration into the design.

Comparators Selection Notes

Select this component when a high-voltage single-channel comparator with push-pull drive capability is required. It is suitable for applications needing rail-to-rail input compatibility and low standby power. Consider the 420 ns propagation delay for timing constraints. Verify that the 40 V maximum supply rating aligns with the system's power distribution network.

Comparators Part Context

This part belongs to the TLV181x-Q1 family of automotive-grade comparators. It shares functional characteristics with other members of the series but differs in channel count and package options. The TLV181x variant specifically provides a push-pull output, distinguishing it from the open-drain TLV182x series within the same product line.

Comparators Replacement Considerations

The TLV1811L-Q1 offers an alternate pinout compatible with legacy devices like the LMC7211. Other family members such as the TLV1812-Q1 provide dual channels in different packages.
