TLV4011QDCKRQ1

Comparators Overview

The TLV4011QDCKRQ1 is an automotive-grade low-power comparator with a precision integrated reference. It operates within a supply voltage range of 1.3 V to 6 V and features a fixed negative-going input threshold voltage (VIT) of 1.226 V with ±1.5% accuracy. The device provides an open-drain active-low RESET output and consumes approximately 4 μA of supply current. It includes built-in hysteresis of 15 mV and supports operation from -40°C to +125°C in a 5-pin SC-70 package.

Comparators Feature Summary

• Integrated precision reference with adjustable thresholds down to 1.226 V
• Open-drain output for flexible logic level interfacing
• Built-in hysteresis to reject input glitches and ensure stable transitions
• Power-on reset assertion when supply voltage exceeds 0.8 V

Comparators Applications

• Emergency Call (eCall) systems
• Telematics control units
• On-Board Charger (OBC) and wireless charger monitoring
• DC/DC converter supervision
• Battery Management System (BMS) undervoltage detection

Comparators Procurement Notes

Verify the specific ordering suffix 'DCKRQ1' corresponds to the SC-70 package and tape-and-reel quantity of 3000 units. Confirm AEC-Q100 qualification status and temperature grade requirements match the target application environment. Ensure pull-up resistor values are selected according to the driving logic's input specifications to maintain valid logic levels.

Comparators Selection Notes

Select this component for applications requiring precise undervoltage monitoring with minimal quiescent current. The fixed 1.226 V internal reference simplifies design by reducing external component count compared to comparators requiring external references. Verify that the required threshold voltage aligns with the available factory-trimmed options or can be achieved via external resistor dividers.

Comparators Part Context

This part belongs to the TLV4011-Q1 family of low-power comparators designed specifically for automotive environments. It complements other Texas Instruments voltage monitoring solutions by offering a balance of high accuracy and low power consumption. The device is characterized for harsh automotive conditions, ensuring reliability in engine compartments and battery systems.

Comparators Replacement Considerations

The catalog version TLV4011 serves as the non-automotive equivalent. Verify that the replacement meets all functional electrical parameters and package dimensions. Note that the catalog version lacks the specific automotive qualification and extended temperature characterization required for safety-critical vehicle systems.
