TLV3012BIDCKR

Comparators Overview

The TLV3012BIDCKR is a low-power, push-pull output comparator from the 'B' version family. It features an integrated 1.242 V voltage reference with 1% initial accuracy and 100 ppm/°C drift. Key electrical parameters include a maximum quiescent current of 3.1 μA, a supply voltage range of 1.65 V to 5.5 V, and a propagation delay of 4 μs (max). The device offers fail-safe inputs, power-on-reset functionality, and integrated hysteresis of up to 8 mV. It operates within a temperature range of –40°C to +125°C and is housed in a compact SC-70-6 package.

Comparators Feature Summary

• Integrated 1.242 V voltage reference with low temperature drift
• Push-pull output stage for direct logic interfacing
• Fail-safe input protection against open circuits
• Built-in power-on-reset and hysteresis

Comparators Applications

• Lane departure warning systems
• Instrument cluster monitoring
• Toll tag readers
• Asset tracking devices
• Battery management systems

Comparators Procurement Notes

Verify the specific ordering suffix IDCKR corresponds to the SC-70-6 package variant. Confirm that the 'B' designation aligns with the required 1.65 V minimum supply voltage and 3.1 μA quiescent current specifications. Ensure the application environment supports the specified –40°C to +125°C operating temperature range.

Comparators Selection Notes

Select this component when space-constrained designs require a single-supply comparator with an internal reference. The push-pull output eliminates the need for external pull-up resistors. The 'B' version is suitable for applications requiring fail-safe inputs and integrated hysteresis to prevent output oscillation near the threshold.

Comparators Part Context

This part belongs to the TLV3011/TLV3012 family of nanopower comparators. The TLV3012 variant specifically provides a push-pull output, distinguishing it from the open-drain TLV3011. The 'B' suffix indicates enhanced features such as lower supply voltage operation and integrated hysteresis compared to standard versions.

Comparators FAQ

What is the function of the REF pin on the TLV3012BIDCKR?

The REF pin provides access to the uncommitted on-chip 1.242 V series voltage reference, which can be used as a stable threshold for the comparator or other circuit components.

How does the fail-safe input feature benefit the TLV3012BIDCKR?

The fail-safe inputs ensure that if the input pins are left open or disconnected, the output assumes a defined state, preventing erratic behavior in safety-critical applications like lane departure warnings.
