TLV1811DCKR

Comparators Overview

The TLV1811DCKR is a single-channel analog comparator from the Texas Instruments TLV181x family, housed in an SC-70 (SOT-353) package. It features rail-to-rail inputs and a push-pull output stage. The device operates on a supply voltage range of 2.4 V to 40 V with a quiescent current of 5 µA per channel. Key electrical specifications include a typical propagation delay of 420 ns, an input offset voltage of 500 µV, and an input bias current of 150 fA. It supports a full operating temperature range from -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input capability extending beyond supply rails for flexible signal interfacing
• Integrated Power-On Reset (POR) circuit ensuring known output states during power transitions
• Push-pull output stage capable of sourcing and sinking milliamps of current without external pull-up resistors

Comparators Applications

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

Comparators Procurement Notes

Verify the specific ordering suffix DCKR corresponds to the SC-70-6 package variant with reversed supplies and shifted V-. Confirm that the component meets functional safety documentation requirements if utilized in safety-critical designs. Ensure input signals are current-limited to prevent damage to internal ESD clamps when voltages exceed supply rails.

Comparators Selection Notes

Select this component for applications requiring high-voltage operation up to 40 V with minimal power consumption. The push-pull output is suitable for driving capacitive loads like MOSFET gates or LEDs directly. Consider the alternate pinout TLV1811L if upgrading from legacy devices such as the LMC7211 family. Verify thermal performance within the SC-70 package for the intended ambient conditions.

Comparators Part Context

This part belongs to the TLV181x/TLV182x family of 40 V rail-to-rail input comparators. The TLV181x series specifically provides push-pull outputs, whereas the TLV182x series offers open-drain options. The family shares common characteristics including micro-power operation, low offset voltage, and integrated Power-On Reset functionality across single, dual, and quad channel configurations.
