TLV4041R5DBVR

Comparators Overview

The TLV4041R5DBVR is a single-channel, low-power 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 draws a maximum quiescent current of 3.5 µA. The device includes a fixed threshold of 3.2 V and offers reference accuracy options at 0.2 V, 0.5 V, and 1.2 V. It exhibits a maximum propagation delay of 360 ns and provides 20 mV of hysteresis. Designed for compact applications, it is housed in an SC-74A (SOT-753) package and supports operating temperatures from -40°C to +125°C.

Comparators Feature Summary

• Integrates a precision voltage reference with multiple selectable output levels
• Features a fixed internal threshold for simplified circuit design
• Provides inherent hysteresis to prevent output oscillation during noise conditions

Comparators Applications

• Battery-powered portable devices requiring minimal power consumption
• Threshold detection circuits in industrial monitoring systems
• Temperature sensing interfaces using thermistor-based dividers

Comparators Procurement Notes

Verify the specific suffix or variant code to confirm the exact reference voltage value, as the family supports multiple precision outputs. Ensure the selected component matches the required thermal performance for the intended operating environment. Confirm package compatibility with the target PCB footprint before finalizing procurement orders.

Comparators Selection Notes

Select this component when system constraints demand ultra-low quiescent current alongside precise voltage monitoring capabilities. The integrated reference eliminates external resistor networks, reducing board space and component count. Consider the fixed threshold limitation if variable trip points are required, in which case a standard comparator might be more suitable.

Comparators Part Context

This part belongs to the TLV40x1 series of small-size, low-power comparators designed by Texas Instruments. The series emphasizes energy efficiency and integration, making it suitable for modern portable electronics where battery life and physical size are critical design parameters.

Comparators Replacement Considerations

Direct substitutes include other parts within the TLV40x1 family that share the SOT-753 package and similar electrical characteristics. Verify pinout compatibility and reference voltage specifications when evaluating alternative sources.
