TLV3011BIDBVR

Comparators Overview

The TLV3011BIDBVR is a low-power analog comparator featuring an open-drain output and an integrated 1.242 V voltage reference with 1% initial accuracy. It operates on a single supply from 1.65 V to 5.5 V, drawing a maximum quiescent current of 3.1 μA. The device includes fail-safe inputs, power-on-reset functionality, and integrated hysteresis. It provides a common-mode input range extending 200 mV beyond the supply rails and supports operation across a temperature range of –40°C to +125°C.

Comparators Feature Summary

• Integrated 1.242 V voltage reference with low temperature drift
• Fail-safe inputs for robust signal detection
• Built-in hysteresis to prevent output oscillation
• Power-on-reset circuitry for reliable startup

Comparators Applications

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

Comparators Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the presence of the 'B' version features, such as fail-safe inputs and integrated hysteresis, which distinguish it from standard versions. Ensure compatibility with the target PCB footprint for the SC-70 or SOT-23 package before finalizing procurement.

Comparators Selection Notes

Select this component when ultra-low static current consumption is critical for battery-operated applications. The integrated voltage reference eliminates the need for external components, reducing board space. Choose this part over standard comparators if fail-safe inputs and built-in hysteresis are required to ensure stable operation in noisy environments without additional circuitry.

Comparators Part Context

This device belongs to the TLV3011/TLV3012 family of low-power comparators. The 'B' variant specifically enhances the baseline design by adding advanced features like fail-safe inputs and integrated hysteresis while lowering the minimum operating voltage. It serves as a compact solution for portable electronics where power efficiency and minimal component count are primary design constraints.

Comparators Replacement Considerations

Standard TLV3011 variants lack the fail-safe inputs and integrated hysteresis found in the 'B' version. Verify that any substitute maintains the 1.65 V minimum supply voltage requirement and the open-drain output configuration to ensure functional equivalence in existing designs.
