TLV4082DBVR

Comparators Overview

The TLV4082DBVR is a dual-channel, low-power analog comparator from Texas Instruments housed in a 6-pin SOT-23 package. It operates on a supply voltage range of 1.5 V to 5.5 V with a typical quiescent current of 2 µA. The device features high threshold accuracy within ±1% over the -40°C to +125°C temperature range and includes an integrated hysteresis of 60 mV. It utilizes open-drain outputs capable of being pulled up to 5.5 V independent of the supply voltage.

Comparators Feature Summary

• Dual-channel architecture with integrated precision reference thresholds for stable voltage monitoring
• Open-drain output topology allowing flexible logic level interfacing via external pull-up resistors
• Built-in 60 mV hysteresis to reject input glitches and ensure noise immunity without external components

Comparators Applications

• Electricity meters
• Thermostats
• Cordless power tools
• Circuit breakers

Comparators Procurement Notes

Verify the specific ordering suffix DBVR corresponds to the SOT-23 package variant when sourcing. Confirm that system designs include appropriate external pull-up resistors for the open-drain outputs. Ensure the application environment remains within the specified operating temperature range of -40°C to +125°C for guaranteed performance specifications.

Comparators Selection Notes

Select this component when a dual-channel solution is required for monitoring two distinct voltage rails simultaneously. The open-drain output configuration is suitable for systems requiring wired-OR logic or interface compatibility with different voltage domains. Consider the low quiescent current for battery-operated applications where power efficiency is critical.

Comparators Part Context

This part belongs to the TLV40x2 family of micro-power comparators. It shares functional similarities with the TLV4062 but differs in output stage topology. The family is designed for space-constrained applications requiring high accuracy and low power consumption in small surface-mount packages.

Comparators Replacement Considerations

The TLV4062DBVR serves as a direct pin-compatible alternative within the same family, offering identical electrical characteristics except for its push-pull output stage which eliminates the need for external pull-up resistors.
