TLV4051R5DBVR

Comparators Overview

The TLV4051R5DBVR is a low-power, high-accuracy comparator from the Texas Instruments TLV40x1 family. It features an inverting input configuration and a push-pull output stage. The device includes a factory-trimmed precision reference with a fixed threshold of 0.5 V. It operates within a supply voltage range of 1.6 V to 5.5 V and consumes a quiescent current of 2 µA. The propagation delay is specified at 360 ns. The component is housed in a SOT-23 (5-pin) package and supports an operating temperature range from –40°C to +125°C.

Comparators Feature Summary

• Integrates a factory-trimmed precision reference for accurate switching thresholds without external components.
• Features a push-pull output stage capable of driving loads directly without requiring pull-up resistors.
• Includes built-in hysteresis to reject input glitches and ensure stable operation in noisy environments.
• Provides known startup conditions via a Power-on-Reset circuit during power supply ramping.

Comparators Applications

• Lithium ion battery monitoring
• Battery management and protection systems
• Current and voltage sensing circuits
• System control and monitoring

Comparators Procurement Notes

Verify the specific ordering suffix DBVR corresponds to the SOT-23-5 tape-and-reel packaging format required for automated assembly. Confirm that the R5 designation matches the necessary 0.5 V reference threshold for the design. Ensure the inverting input topology aligns with the signal conditioning requirements before finalizing procurement.

Comparators Selection Notes

Select this component when a compact solution with a precise 0.5 V threshold is required. The push-pull output eliminates the need for external pull-up resistors, simplifying the schematic. Consider the inverting logic state where the output goes low when the input exceeds the reference. Verify that the 2 µA quiescent current meets the system's power budget constraints.

Comparators Part Context

This part belongs to the TLV40x1 family of small-size, low-power comparators designed for space-critical designs. The family offers various combinations of input configurations (inverting/non-inverting), output types (open-drain/push-pull), and reference voltages (0.2 V, 0.5 V, 1.2 V). The TLV4051 specifically combines the inverting input with the push-pull output and 0.5 V reference options.

Comparators Replacement Considerations

Compatible substitutes within the same family include TLV4041R5DBVR, which shares the 0.5 V reference but utilizes a non-inverting input configuration instead of the inverting input found in the TLV4051R5DBVR.
