TLV1811LQDBVRQ1

Comparators Overview

The TLV1811LQDBVRQ1 is a single-channel automotive-grade analog comparator from the TLV181x-Q1 family, manufactured by Texas Instruments. It features rail-to-rail inputs and a push-pull output stage. The device operates within a supply voltage range of 2.4 V to 40 V with a quiescent current of 5 μA per channel. Key electrical specifications include an input offset voltage of 500 μV, a typical propagation delay of 420 ns, and a power-on reset (POR) function for known start-up states. It is housed in a SOT-23-5 package.

Comparators Feature Summary

• Qualified for automotive applications with AEC-Q100 Grade 1 certification
• Rail-to-rail input capability extending beyond supply rails
• Integrated Power-On Reset (POR) ensures known output state during power transitions
• Push-pull output stage capable of sourcing and sinking milliamps of current

Comparators Applications

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

Comparators Procurement Notes

Verify the specific 'L' suffix indicates the alternate pinout configuration compatible with legacy devices like LMC7211 or TLV7211. Confirm the DBVR package designation corresponds to the SOT-23-5 form factor. Ensure the Q1 suffix matches the required automotive qualification standards for your specific application environment.

Comparators Selection Notes

Select this component when high voltage tolerance up to 40 V is required alongside low power consumption. The push-pull output eliminates the need for external pull-up resistors, simplifying board design. The alternate pinout facilitates direct upgrades from older comparator families without redesigning the PCB footprint.

Comparators Part Context

This part belongs to the TLV18xx-Q1 family of micro-power comparators. The family includes dual and quad variants as well as open-drain output options (TLV182x-Q1). The TLV1811L-Q1 specifically provides a single channel with a non-standard pinout to support backward compatibility with previous generation components.

Comparators Replacement Considerations

The TLV1811LQDBVRQ1 serves as a pin-compatible replacement for the LMC7211 and TLV7211. Designers upgrading from these legacy parts should verify that the new input bias currents and ESD protection characteristics meet system requirements.
