TLV9024QPWRQ1

Comparators Overview

The TLV9024QPWRQ1 is an automotive-grade quad precision analog comparator from Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and supports ambient temperatures from -40°C to +125°C. The device features a typical propagation delay of 100 ns and a low quiescent current of 16 μA per channel. Input offset voltage is specified at 300 μV, with rail-to-rail input capability extending beyond the supply rails. It utilizes an open-drain output configuration housed in a TSSOP-14 package.

Comparators Feature Summary

• Precision input stage with low offset voltage for accurate threshold detection
• Integrated Power-On Reset (POR) ensures known output states during system startup
• Fault-tolerant inputs withstand voltages up to 6 V without damage or phase inversion
• Open-drain outputs allow flexible pull-up configurations for logic translation

Comparators Applications

• Hybrid electric vehicle (HEV) and electric vehicle (EV) power train systems
• Automotive infotainment and instrument cluster circuits
• Body control module signal monitoring

Comparators Procurement Notes

Verify that the component matches the specific TLV9024QPWRQ1 designation to ensure correct quad-channel configuration and open-drain output type. Confirm the TSSOP-14 package variant aligns with board layout requirements. Ensure compliance with AEC-Q100 Grade 1 standards for the intended automotive temperature range. Cross-reference datasheet revision dates to confirm updated electrical characteristics.

Comparators Selection Notes

Select this component when high precision is required alongside low power consumption in automotive environments. The open-drain output necessitates an external pull-up resistor, which allows level shifting to voltages exceeding the supply rail. Consider the 100 ns propagation delay against system timing requirements. Verify that the fault-tolerant input range meets the maximum expected signal levels in noisy environments.

Comparators Part Context

This part belongs to the TLV902x-Q1 family of precision automotive comparators. It shares architectural similarities with the TLV903x-Q1 series, differing primarily in output stage topology. While the TLV903x-Q1 offers push-pull outputs, the TLV902x-Q1 provides open-drain outputs suitable for wired-OR configurations. The family is designed to replace legacy comparators requiring higher precision and better noise immunity.

Comparators Replacement Considerations

Direct functional substitutes include other members of the TLV902x-Q1 family, such as the dual-channel TLV9022QPWRQ1, if fewer channels are sufficient. For applications requiring push-pull outputs instead of open-drain, the TLV9034QPWRQ1 serves as a compatible alternative within the same precision family.
