TLV1814PWR

Comparators Overview

The TLV1814PWR is a quad micro-power high-voltage analog comparator manufactured by Texas Instruments. It features rail-to-rail inputs and push-pull outputs, operating on a single supply voltage ranging from 2.4 V to 40 V. The device draws a typical quiescent current of 7 uA per channel. Key electrical specifications include a maximum input offset voltage of 500 uV, an input bias current of 0.15 pA, and a propagation delay of 900 ns. It provides a 10 mA output drive capability and maintains a power supply rejection ratio of 100 dB across the specified temperature range.

Comparators Feature Summary

• Supports high-voltage operation with a wide single-supply range up to 40 V
• Features rail-to-rail input capability for maximum dynamic range
• Delivers push-pull output stages with 10 mA drive strength
• Maintains ultra-low quiescent current consumption for energy efficiency

Comparators Applications

• High-voltage signal monitoring in industrial systems
• Battery management system threshold detection
• Over-voltage protection circuits
• Sensor interface applications requiring low power

Comparators Procurement Notes

Verify the specific package variant, as the TLV1814 series includes TSSOP-14 and SOIC-14 options. Confirm that the required propagation delay and offset voltage parameters align with the standard TLV1814 specifications rather than higher-performance variants like the TLV3214. Ensure the design accounts for the 40 V maximum supply limit and thermal dissipation requirements for the chosen surface-mount package.

Comparators Selection Notes

Select this component when high-voltage tolerance and low power consumption are primary constraints. The rail-to-rail input stage simplifies interfacing with various sensors without level shifting. Compare against faster comparers if propagation delay exceeds application limits, or consider lower-cost general-purpose devices if the high-voltage rating and precision offset are not strictly necessary.

Comparators Part Context

This part belongs to the TLV1814 family of micro-power comparators designed for automotive and industrial environments. It offers a balance of speed, precision, and power efficiency. The quad configuration allows multiple comparison functions within a single compact package, reducing board space compared to discrete solutions or single-channel alternatives.

Comparators Replacement Considerations

The TLV1814QDRQ1 serves as a qualified automotive-grade alternative with similar functionality but may exhibit different propagation delay characteristics due to package variations.
