TLV1814QPWRQ1

Comparators Overview

The TLV1814QPWRQ1 is an automotive-grade analog comparator featuring four independent channels in a TSSOP-14 package. It operates on a supply voltage range of 2.4 V to 40 V with a quiescent current of 7 uA per channel. Key electrical parameters include a maximum input offset voltage of 500 uV, input bias current of 0.15 pA, and propagation delay of 900 ns. The device supports rail-to-rail inputs, push-pull outputs, and functions within a temperature range of -40°C to +125°C.

Comparators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for high-reliability applications
• High-voltage operation capability up to 40 V supply rails
• Ultra-low power consumption with 7 uA quiescent current per channel
• Rail-to-rail input stage enabling full common-mode voltage range utilization

Comparators Applications

• Battery management systems in electric vehicles
• High-side current sensing circuits
• Over-voltage protection monitoring
• Sensor signal conditioning interfaces

Comparators Procurement Notes

Verify the specific suffix 'PWRQ1' corresponds to the TSSOP-14 package and tape-and-reel orientation. Confirm AEC-Q100 certification status through official Texas Instruments documentation. Ensure design compatibility with the specified 2.4 V to 40 V operating range and thermal requirements for the intended environment.

Comparators Selection Notes

Select this component when high-voltage tolerance and low power are critical. The quad configuration offers space efficiency compared to single-channel alternatives. Consider the 500 uV offset voltage for precision requirements. Verify that the 900 ns propagation delay meets system timing constraints.

Comparators Part Context

Part of the TLV181x family of micropower comparators designed for automotive environments. Shares architectural similarities with TLV1814QDRQ1 but differs in package type (TSSOP vs SOIC) and specific electrical characteristics such as offset voltage and propagation delay.

Comparators Replacement Considerations

TLV1814QDRQ1 serves as a pin-compatible alternative in SOIC-14 packaging. Verify functional equivalence regarding offset voltage and speed specifications before substitution.
