TLV9021DBVR

Comparators Overview

The TLV9021DBVR is a single-channel precision analog comparator from Texas Instruments, housed in a SOT-23-5 package. 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. Key electrical specifications include a typical quiescent current of 17.1 µA, an input offset voltage of ±300 µV, and an input bias current of 5 pA. The device features rail-to-rail inputs with fault tolerance up to 6 V and utilizes an open-drain output configuration.

Comparators Feature Summary

• Features fault-tolerant inputs capable of handling voltages up to 6 V without damage or output phase inversion.
• Provides low input offset voltage for high-precision voltage monitoring applications.
• Offers an open-drain output stage that can be pulled up below or beyond the supply voltage.

Comparators Applications

• Appliances
• Building automation
• Factory automation and control

Comparators Procurement Notes

Verify the specific ordering suffix 'DBVR' corresponds to the SOT-23-5 package and tape-and-reel delivery format. Confirm the component meets RoHS compliance requirements for your region. Ensure the design accounts for the open-drain output requirement by selecting an appropriate external pull-up resistor value based on the target logic levels.

Comparators Selection Notes

Select this component when a single-channel comparator with rail-to-rail inputs and fault tolerance is required. The open-drain output distinguishes it from push-pull variants like the TLV9031. Consider the low quiescent current and precision offset voltage for battery-powered or sensitive measurement circuits operating in harsh environments.

Comparators Part Context

This part belongs to the TLV902x family of precision comparators designed for industrial applications. It shares core performance characteristics with other members of the series but differs in channel count and pinout configurations. The DBVR suffix specifically denotes the surface-mount SOT-23-5 package variant.

Comparators Replacement Considerations

The TLV9021DCKR is a direct substitute offering identical electrical specifications in the SC-70 (DCK) package. Designers must verify pin compatibility during replacement due to potential differences between SOT-23-5 and SC-70 footprints.

Comparators FAQ

What is the maximum voltage the inputs can tolerate?

The inputs are fault-tolerant and can withstand voltages up to 6 V without damage, even if the supply voltage is lower.

Does the TLV9021 have a shutdown mode?

No, the TLV9021 does not feature a shutdown mode; it operates continuously once powered.
