TLV9022QDDFRQ1

Comparators Overview

The TLV9022QDDFRQ1 is an automotive-grade precision dual analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features rail-to-rail input capabilities. The device provides open-drain outputs with a maximum sink current of 100 mA per channel. Key electrical specifications include a typical supply current of 32 uA, an input offset voltage of 1.5 mV, and an input bias current of 5 pA. Propagation delay is specified at 150 ns, with a common-mode rejection ratio of 60 dB and power supply rejection ratio of 95 dB. It functions reliably across an extended temperature range from -40°C to +125°C.

Comparators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• Precision design utilizing rail-to-rail inputs to maximize dynamic range and signal integrity.
• High-drive open-drain output stage capable of sourcing up to 100 mA per channel for direct load interfacing.

Comparators Applications

• Battery management systems requiring precise voltage threshold detection.
• Industrial control circuits needing high-reliability signal comparison.
• Automotive sensor interfaces demanding low-power operation and wide temperature tolerance.

Comparators Procurement Notes

Verify the specific suffix DDFFRQ1 to confirm the SOT-23-THIN-8 package variant. Ensure procurement channels provide valid AEC-Q100 certification documentation. Confirm that the ordering quantity aligns with the manufacturer's standard reel sizes or cut tape availability requirements for this specific automotive component.

Comparators Selection Notes

Select this component when high drive capability is required alongside precision comparison. The open-drain output allows flexible voltage level shifting compared to push-pull alternatives. Consider the 1.65 V minimum supply voltage for ultra-low power applications where other comparators may require higher thresholds. Evaluate the 100 mA output current against load requirements to ensure adequate drive strength without external buffering.

Comparators Part Context

This part belongs to the TLV902x family of precision comparators designed for automotive and industrial markets. It shares architectural similarities with the TLV9022QPWRQ1 but utilizes a different surface-mount package. The Q suffix indicates automotive qualification, while the DDFFRQ1 designation specifies the thin small-outline transistor package configuration suitable for space-constrained PCB layouts.

Comparators Replacement Considerations

The TLV9022QPWRQ1 serves as a functional equivalent offering identical electrical characteristics in a TSSOP-8 package. Verify pinout compatibility and thermal dissipation requirements when substituting between package types. No other direct cross-model replacements are confirmed in available public documentation.
