TLV3691IDCKR

Comparators Overview

The TLV3691IDCKR is a single-channel analog comparator from Texas Instruments housed in a SC70-5 package. It operates on a supply voltage ranging from 0.9 V to 6.5 V with a maximum quiescent current of 150 nA at 25°C and 200 nA across the industrial temperature range of -40°C to +125°C. The device features rail-to-rail inputs extending 100 mV beyond both rails, a push-pull output stage, and an input offset voltage of ±15 mV (max) at 25°C. Propagation delay is typically 24 µs.

Comparators Feature Summary

• Rail-to-rail input common-mode range extends 100 mV beyond both power supply rails without phase inversion.
• Push-pull output stage eliminates the need for external pull-up resistors.
• Internal hysteresis reduces sensitivity to noise in signal transitions.

Comparators Applications

• Overvoltage and undervoltage detection
• Window comparators
• Overcurrent detection
• Zero-crossing detection
• System monitoring for portable medical devices

Comparators Procurement Notes

Verify the specific ordering suffix 'DCKR' corresponds to the SC70-5 package and reel packaging configuration required for your assembly process. Confirm that the component meets RoHS compliance standards applicable to your region. Ensure design validation accounts for the specified humidity sensitivity level indicated in the datasheet.

Comparators Selection Notes

Select this component when ultra-low power consumption is critical alongside wide supply voltage flexibility. The rail-to-rail input capability allows for direct interfacing with signals exceeding the supply rails. The compact SC70-5 package is suitable for space-constrained portable electronics and industrial sensor applications requiring high reliability.

Comparators Part Context

The TLV3691 belongs to the nano-power comparator family designed for battery-operated systems. It complements other low-power analog components by providing precise threshold detection with minimal energy drain. The device supports industrial temperature ranges, making it suitable for harsh environments where standard commercial-grade parts may fail.

Comparators Replacement Considerations

Direct pin-compatible replacements within the same series include TLV3691IDCKT. Verify package dimensions and electrical characteristics against the original design requirements before substitution.

Comparators FAQ

Does the TLV3691 exhibit phase inversion when input voltages exceed the supply rails?

No, the device is designed to prevent phase inversion even when input pins exceed the supply voltage by up to 100 mV.

What is the typical internal hysteresis value of the TLV3691?

The typical internal hysteresis is 17 mV, which helps reduce comparator sensitivity to noise.
