TLV3702CDGKR

Comparators Overview

The TLV3702CDGKR is a dual nanopower comparator from Texas Instruments featuring push-pull CMOS outputs. It operates on a single supply voltage ranging from 2.5V to 16V, with a typical supply current of 560nA per channel. The device supports an input common-mode range extending from -0.1V to VCC + 5V and includes reverse battery protection up to 20V. Packaged in an 8-pin SOIC (D) format with tape-and-reel suffix 'R', it is rated for commercial temperatures from 0°C to 70°C.

Comparators Feature Summary

• Nanopower consumption with only 560nA per channel supply current
• Push-pull CMOS output stage eliminating the need for external pull-up resistors
• Input common-mode range exceeds supply rails, extending to VCC + 5V
• Reverse battery protection capability up to 20V

Comparators Applications

• Portable battery monitoring systems
• Consumer medical electronics
• Security detection systems
• Handheld instruments
• Ultra-low power wireless applications

Comparators Procurement Notes

Verify that the C-suffix designation confirms the commercial temperature range of 0°C to 70°C rather than the industrial grade. Ensure the 'R' suffix matches the required tape-and-reel packaging configuration for automated assembly processes. Confirm the specific package type corresponds to the standard 8-pin SOIC footprint.

Comparators Selection Notes

Select this component when minimizing quiescent current is critical for battery life. The rail-to-rail input capability allows operation at low supply voltages without limiting the input voltage range. The integrated push-pull output simplifies circuit design by removing the requirement for discrete pull-up components.

Comparators Part Context

This device belongs to the TLV370x family of nanopower comparators, which also includes single-channel (TLV3701) and quad-channel (TLV3704) variants. The family shares identical electrical characteristics and features, differing primarily in the number of channels and available package options such as SOT-23, MSOP, and TSSOP.

Comparators Replacement Considerations

The TLC3702 offers similar functionality but utilizes open-drain outputs and consumes significantly higher current. Verify if the system can accommodate the additional external pull-up resistor required by the TLC3702 architecture.
