TLV3704IPW

Comparators Overview

The TLV3704IPW is a quad nanopower voltage comparator from Texas Instruments, housed in a 14-pin TSSOP package. It operates on a single supply ranging from 2.5V to 16V or split supplies of ±1.25V to ±8V. The device features push-pull CMOS outputs and an input common-mode range extending from –0.1V to VCC + 5V. It draws only 560nA per channel at 25°C, with a maximum input offset voltage of 5mV and propagation delays typically around 34µs to 45µs.

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
• Reverse battery protection up to 20V for harsh environment robustness
• Integrated Power-on-Reset circuitry ensures known start-up conditions

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 IPW confirms the Industrial temperature grade (-40°C to 125°C) and TSSOP packaging. Confirm availability status as product lifecycles may change. Ensure design compatibility with the specified 2.5V minimum operating voltage for extended industrial ranges.

Comparators Selection Notes

Select this component when nanowatt quiescent current is critical for battery life. The over-the-rail input capability allows signal comparison even when input voltages exceed the positive supply rail. Push-pull outputs eliminate the need for external pull-up resistors, simplifying board layout and reducing component count.

Comparators Part Context

This part belongs to the TLV370x family of nanopower comparators, which includes single (TLV3701), dual (TLV3702), and quad (TLV3704) configurations. The IPW suffix denotes the industrial temperature range variant packaged in a 14-pin Thin Shrink Small Outline Package (TSSOP).

Comparators Replacement Considerations

The TLC3704 offers similar quad comparator functionality but consumes significantly higher current (9µA/channel) and lacks the over-the-rail input feature. Verify if the increased power consumption is acceptable for the target application before substituting.

Comparators FAQ

What is the input common-mode voltage range?

The input common-mode range extends from –0.1V to VCC + 5V, allowing operation above the positive supply rail without damage.

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

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

Is reverse battery protection included?

Yes, the device provides reverse battery protection up to 20V, guarding against overcurrent conditions from improper battery installation.
