TLV9022QDGKRQ1

Comparators Overview

The TLV9022QDGKRQ1 is an automotive-grade dual-channel precision analog comparator from Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range of -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. The output stage utilizes an open-drain configuration.

Comparators Feature Summary

• Qualified for automotive applications under AEC-Q100 standards
• Includes Power-On Reset (POR) circuitry for known start-up states
• Features fault-tolerant inputs capable of withstanding up to 6 V without damage
• Open-drain output allows pull-up voltages below or beyond the supply voltage

Comparators Applications

• HEV/EV and power train systems
• Infotainment and cluster modules
• Body control modules

Comparators Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm the component meets the exact AEC-Q100 grade requirements for your target application environment. Ensure compatibility with your system's logic levels given the open-drain output architecture.

Comparators Selection Notes

Select this component when high precision and low power consumption are critical in automotive environments. The open-drain output is suitable for interfacing with various logic families via external pull-up resistors. Consider the thermal characteristics of the VSSOP-8 package if operating near maximum temperature limits.

Comparators Part Context

This part belongs to the TLV902x-Q1 family of precision comparators designed specifically for harsh automotive environments. It shares core electrical characteristics with other members of the series but differs in pinout and package options. The DGKRQ1 suffix indicates a VSSOP-8 package variant intended for surface-mount assembly.

Comparators FAQ

What is the input voltage range relative to the supply rails?

The common-mode voltage range extends from (V–) – 0.2 V to (V+) + 0.2 V, allowing rail-to-rail operation with slight overdrive capability.

How does the Power-On Reset feature function?

The POR ensures the output remains in a known state until the minimum supply voltage is reached, preventing output transients during system power-up and power-down.
