TLV3702IDGKG4

Comparators Overview

The TLV3702IDGKG4 is a dual nanopower push-pull output comparator from Texas Instruments. It operates on a single supply voltage ranging from 2.5V to 16V, with an extended industrial temperature range of -40°C to +125°C. The device draws only 560nA per channel of supply current. It features an input common-mode range extending from -0.1V to VCC + 5V and includes reverse battery protection up to 20V. The package is an 8-pin VSSOP.

Comparators Feature Summary

• Nanopower consumption with 560nA per channel supply current
• Push-pull CMOS output stage for direct logic interfacing
• Input common-mode range exceeds the rails by up to 5V
• Reverse battery protection up to 20V

Comparators Applications

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

Comparators Procurement Notes

Verify the specific suffix 'DGKG4' corresponds to the 8-pin VSSOP package and industrial temperature grade (-40°C to +125°C). Confirm RoHS compliance status as indicated in official documentation. Ensure design compatibility with the specified 2.5V to 16V supply range and check absolute maximum ratings against system stress conditions.

Comparators Selection Notes

Select this component when low quiescent current is critical for battery life. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. The over-the-rail input capability allows signal comparison even when input voltages exceed the positive supply rail, simplifying circuit design in varying supply environments.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, which also includes single (TLV3701) and quad (TLV3704) variants. The family shares core electrical characteristics such as low supply current and high input impedance. The TLV3702 specifically provides two independent channels in an 8-pin form factor, balancing channel count with package size constraints.

Comparators Replacement Considerations

The TLV3402IDGKG4 is a documented alternative within the same datasheet comparison table. Note that the TLV3402 utilizes an open-drain output stage rather than the push-pull configuration found in the TLV3702, requiring different external circuit considerations.
