TLV3701IP

Comparators Overview

The TLV3701IP is a single-channel nanopower analog comparator from Texas Instruments, housed in an 8-pin PDIP package. It operates on a supply voltage range of 2.5V to 16V and features a push-pull CMOS output stage. The device draws a typical supply current of 560nA per channel. Input common-mode voltage extends from -0.1V to VCC + 5V, providing reverse battery protection up to 20V. The industrial temperature grade (I-suffix) supports operation between -40°C and +125°C with a maximum input offset voltage of 5mV at 25°C.

Comparators Feature Summary

• Nanopower consumption with only 560nA supply current per channel for extended battery life
• Over-the-rail input capability allowing signals up to VCC + 5V without damage
• Integrated power-on-reset circuitry ensures known start-up conditions
• Fail-safe inputs maintain high impedance even when the power supply is unpowered

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 ordering suffix 'IP' corresponds to the Plastic DIP (PDIP) package variant rather than surface-mount options like DBV or D. Confirm the 'I' suffix indicates the industrial temperature range (-40°C to +125°C). Ensure the datasheet revision matches the specific manufacturing lot requirements for your design implementation.

Comparators Selection Notes

Select this component when low quiescent current is critical compared to speed requirements. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the PDIP package only if through-hole mounting is required; otherwise, surface-mount alternatives offer smaller footprints. Verify that the 5mV offset voltage meets the precision needs of the threshold detection application.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, which includes dual (TLV3702) and quad (TLV3704) variants. The family shares identical electrical characteristics but differs in channel count and packaging options such as SOIC, MSOP, and TSSOP. The TLV3701IP specifically provides the single-channel configuration in a traditional through-hole package suitable for prototyping or legacy board designs.

Comparators Replacement Considerations

Comparators FAQ

How does the over-the-rail input feature benefit system design?

It allows the input voltage to exceed the positive supply rail by up to 5V without damaging the device, enabling direct sensing of higher voltage signals without additional attenuation circuits.

What is the function of the internal Power-On-Reset circuit?

The POR circuit holds the output low for approximately 3ms after the supply voltage crosses 1.5V, ensuring the comparator remains in a known state during power-up transitions.
