Texas Instruments TLV3704IPWR

Overview

TLV3704IPWR from Texas Instruments is a quad nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-powered systems. It draws only 560 nA per channel, operates from 2.5 V to 16 V, supports input common-mode voltage up to VCC + 5 V, and is rated for –40°C to +125°C industrial temperature range - enabling use in portable medical devices and security sensors.

For engineers reviewing the TLV3704IPWR datasheet, TLV3704IPWR pinout, TLV3704IPWR application, or TLV3704IPWR equivalent, key selection criteria include its rail-overlapping input range, reverse-battery protection, propagation delay under 50 µs at 10 mV overdrive, and compatibility with single-supply 5 V or 12 V systems requiring stable low-quiescent-current comparators.

Technical Context

The TLV3704IPWR implements a precision nanopower comparator core with fail-safe inputs capable of operating 5 V above VCC without damage, enabled by internal ESD clamps and power-rail-independent biasing. Its push-pull output stage eliminates external pull-up resistors and delivers rail-to-rail sourcing/sinking capability up to ±50 µA.

An integrated Power-On Reset (POR) circuit holds outputs low for up to 3 ms during supply ramp-up, ensuring deterministic startup behavior. Input offset voltage is specified at 250 µV (typ), with hysteresis of 1–5 mV and CMRR up to 88 dB across full supply range - supporting accurate threshold detection in noisy, low-voltage environments.

FAQ

What is the maximum input voltage allowed on TLV3704IPWR pins relative to VCC?

The TLV3704IPWR supports an input common-mode voltage range from –0.1 V to VCC + 5 V. This means inputs can safely exceed the positive supply rail by up to 5 V - critical for monitoring battery voltage without external level-shifting circuitry. Absolute maximum input voltage is limited to 20 V, whichever is smaller between VCC + 5 V and 20 V, as specified in the absolute maximum ratings table of the TLV3704IPWR datasheet.

Does TLV3704IPWR require external pull-up resistors on its outputs?

No, TLV3704IPWR does not require external pull-up resistors because it features a push-pull CMOS output stage. Each of its four outputs can actively drive high (to within 80 mV of VCC) and low (to within 8 mV of GND) without external components. This reduces system power consumption, simplifies PCB layout, and eliminates resistor tolerance-induced timing uncertainty - a key advantage over open-drain comparators like the TLC3704.

What is the typical propagation delay of TLV3704IPWR at 12 V supply and 50 mV input overdrive?

At VCC = 12 V and 50 mV input overdrive, the TLV3704IPWR exhibits a typical propagation delay of 16 µs for both high-to-low and low-to-high transitions, as confirmed in Section 6.8 of the official datasheet. This value remains consistent across the full industrial temperature range (–40°C to +125°C), making it predictable for timing-critical threshold detection in battery management and safety interlock circuits.

Can TLV3704IPWR operate with a 2.5 V single supply?

Yes, TLV3704IPWR is fully specified to operate from a minimum single supply of 2.5 V across the commercial temperature range (0°C to 70°C) and 2.7 V across the industrial range (–40°C to +125°C). At 2.5 V, it maintains 560 nA typical supply current, 250 µV typical input offset voltage, and functional push-pull outputs - enabling direct integration into low-voltage energy-harvesting and coin-cell–powered systems without voltage boosting.

How does the Power-On Reset (POR) function behave on TLV3704IPWR?

The TLV3704IPWR incorporates an internal Power-On Reset (POR) circuit that holds all four outputs low for up to 3 ms after VCC crosses 1.5 V during power-up or brownout recovery. This ensures deterministic startup behavior and prevents spurious logic transitions in connected microcontrollers or FPGAs. The POR is active only during supply ramping - once VCC stabilizes above the minimum operating voltage, output states reflect real-time input comparisons without delay.
