TLV4021R2YKAR

Comparators Overview

The TLV4021R2YKAR is a single-channel comparator from Texas Instruments featuring an integrated precision voltage reference. It operates within a supply voltage range of 1.6 V to 5.5 V and utilizes a 4-pin DSBGA package. The device includes a fixed threshold of 3.2 V alongside precision reference options at 0.2 V, 0.5 V, and 1.2 V. It offers rail-to-rail input/output capabilities with an open-drain output configuration, designed for low-power applications requiring high accuracy in compact form factors.

Comparators Feature Summary

• Integrates a precision voltage reference with multiple fixed threshold options for simplified circuit design
• Features rail-to-rail input and output stages compatible with various logic families
• Utilizes an open-drain output structure for flexible interfacing and level shifting

Comparators Applications

• Undervoltage protection circuits
• Threshold detection systems
• Battery monitoring applications

Comparators Procurement Notes

Verify the specific suffix 'R2' indicates the fixed 3.2 V threshold variant when ordering. Confirm the DSBGA-4 package type matches your PCB footprint requirements. Ensure the open-drain output configuration aligns with your downstream logic interface needs. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Comparators Selection Notes

Select this component when a small footprint and integrated reference are required. The fixed 3.2 V threshold eliminates external resistor networks. Consider the open-drain output if pull-up resistors are acceptable. Evaluate the 1.6 V minimum supply voltage against your system's power rails. The DSBGA package suits space-constrained designs.

Comparators Part Context

This part belongs to the TLV40x1 family of small-size, low-power comparators. The family shares common architectural features but varies by internal reference thresholds and package types. The TLV4021 specifically denotes the single-channel variant with a fixed 3.2 V reference option, distinguishing it from other threshold variants in the series.

Comparators Replacement Considerations

Check for other TLV40x1 variants with different fixed thresholds if 3.2 V is unsuitable. Verify pinout compatibility before substituting with generic comparators. Ensure replacement parts support the 1.6 V to 5.5 V supply range and open-drain output requirement.
