TLV9022QPWRQ1

Comparators Overview

The TLV9022QPWRQ1 is a dual precision analog comparator designed for automotive applications, certified to AEC-Q100 standards. It operates within a supply voltage range of 1.65 V to 5.5 V and features rail-to-rail inputs. Key electrical specifications include an input offset voltage (Vos) of 1.5 mV, input bias current (Ib) of 5 pA, and input offset current (Ios) of 1 pA. The device draws 18 uA of operating supply current per channel. It provides open-drain outputs with a propagation delay of 150 ns. Common-mode rejection ratio (CMRR) is 60 dB, and power supply rejection ratio (PSRR) is 95 dB. It functions reliably across a temperature range of -40°C to +125°C.

Comparators Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 qualification standards
• Precision performance characterized by low input offset voltage and minimal bias currents
• Wide single-supply operation capability from 1.65 V to 5.5 V
• Rail-to-rail input stage enabling full common-mode voltage utilization

Comparators Applications

• Automotive sensor signal conditioning
• Battery management system threshold detection
• Industrial control circuit protection
• Low-voltage monitoring systems

Comparators Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-8 package when sourcing. Confirm AEC-Q100 certification status is required for the target automotive application. Ensure the design accounts for the open-drain output configuration, which necessitates external pull-up resistors for proper logic level translation. Validate that the 1.65 V minimum supply voltage aligns with the system's power rails under all operating conditions.

Comparators Selection Notes

Select this component when high precision is required in low-power automotive environments. The low 18 uA supply current makes it suitable for battery-operated systems where energy conservation is critical. The wide input common-mode range simplifies interface design with various sensors without requiring additional level-shifting circuits. Consider the 150 ns propagation delay if high-speed switching is necessary, as faster alternatives exist.

Comparators Part Context

This part belongs to Texas Instruments' TLV902x family of precision comparators. The 'Q1' suffix denotes automotive qualification. It serves as a dual-channel variant within the series, offering two independent comparison functions in a compact surface-mount package. It complements other devices like the TLV903x series but focuses on ultra-low power and precision rather than higher speed or wider voltage ranges.

Comparators Replacement Considerations

Check for pin-compatible alternatives such as the TLV9022IDR or non-automotive TLV9022 variants if AEC-Q100 certification is not mandatory. Verify that any substitute maintains the same 1.5 mV Vos specification and 18 uA current consumption to ensure system performance parity.
