TLV4041R5YKAR

Comparators Overview

The TLV4041R5YKAR is a low-power, high-accuracy comparator featuring a factory-trimmed 0.5 V precision reference and push-pull output stage. It operates within a supply voltage range of 1.6 V to 5.5 V with a quiescent current of 2 µA. The device provides a propagation delay of 360 ns and includes precision hysteresis for noise immunity. Designed for space-critical applications, it is housed in an ultra-small 0.73 mm × 0.73 mm DSBGA package.

Comparators Feature Summary

• Integrates a factory-trimmed 0.5 V precision reference with specified accuracy tolerances.
• Features a push-pull output stage providing defined logic levels without external pull-up resistors.
• Includes built-in precision hysteresis to reject input glitches and ensure stable digital outputs.
• Provides known startup conditions via a Power-on-Reset (POR) circuit during power transitions.

Comparators Applications

• Lithium ion battery monitoring
• Battery management and protection systems
• Current and voltage sensing circuits
• Point of load regulators
• DC/DC and AC/DC power supplies

Comparators Procurement Notes

Verify the specific ordering suffix YKAR corresponds to the required DSBGA package and tape-and-reel configuration. Confirm that the 0.5 V reference threshold aligns with system requirements. Ensure design compatibility with the 1.6 V to 5.5 V supply range and -40°C to +125°C operating temperature limits.

Comparators Selection Notes

Select this component when a compact footprint is critical due to its 0.73 mm × 0.73 mm DSBGA package. Choose the push-pull output variant if direct driving of subsequent stages is preferred over open-drain configurations. The integrated 0.5 V reference eliminates the need for external resistor dividers for this specific threshold application.

Comparators Part Context

This part belongs to the TLV40x1 family of small-size, low-power comparators. The '4' in the model number indicates a non-inverting input configuration, while the 'R5' suffix denotes the 0.5 V internal reference. The 'YKA' identifies the specific 4-bump DSBGA package type used for space-constrained designs.

Comparators Replacement Considerations

Direct substitutes within the same family include TLV4041R1 (1.2 V reference) and TLV4041R2 (0.2 V reference). For different output topologies, consider TLV4021 variants which feature open-drain outputs instead of push-pull.
