TLV3704IPWRG4

Comparators Overview

The TLV3704IPWRG4 is a quad nanopower comparator from Texas Instruments, featuring push-pull CMOS outputs. 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 at 2.7V. Key electrical characteristics include a maximum input offset voltage of 5mV and an input common-mode range extending from -0.1V to VCC + 5V. It is housed in a 14-pin TSSOP package.

Comparators Feature Summary

• Ultra-low power consumption with 560nA per channel supply current
• Input common-mode range exceeds the positive supply rail by up to 5V
• Integrated Power-on-Reset circuit for controlled start-up conditions
• Fail-safe inputs maintained at high impedance even when unpowered

Comparators Applications

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

Comparators Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm that the 'PW' package designation corresponds to the TSSOP form factor required for your PCB layout constraints before finalizing procurement.

Comparators Selection Notes

Select this component when minimizing quiescent current is critical for battery life. The over-the-rail input capability allows signal comparison above the supply voltage without external components. Ensure the propagation delay specifications meet the timing requirements of your application, as nanopower devices typically exhibit slower response times than higher-current comparators.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, which includes single (TLV3701), dual (TLV3702), and quad (TLV3704) configurations. The IPWRG4 variant specifically denotes the industrial temperature grade (-40°C to +125°C) and the TSSOP-14 package. It serves as a low-power alternative to the TLC3704 series, offering significantly lower supply current at the cost of increased propagation delay.

Comparators Replacement Considerations

The TLC3704IDR is a compatible replacement within the same manufacturer portfolio. Note that the TLC3704 series offers faster propagation delays but consumes significantly more supply current (9µA vs 560nA). Verify that the increased power consumption aligns with your system's thermal and battery life requirements.

Comparators FAQ

What is the input common-mode voltage range?

The input common-mode range extends from -0.1V to VCC + 5V, allowing operation even when input signals exceed the positive supply rail.

How does the Power-on-Reset (POR) function operate?

The internal POR circuit holds the output low for approximately 3ms after the supply voltage crosses 1.5V, ensuring a known state during power-up or power-down sequences.

Is the device suitable for harsh environments with reverse battery connections?

Yes, the device features reverse battery protection up to 20V, guarding against overcurrent conditions caused by improper battery installation.
