Texas Instruments TLV3404IDR

Overview

TLV3404IDR from Texas Instruments is a quad nanopower open-drain comparator with 470 nA per channel supply current, rail-to-rail input range (–0.1 V to VCC + 5 V), and operation across 2.5 V to 16 V supply. It supports industrial temperature range (–40°C to +125°C) and features reverse battery protection up to 18 V - ideal for ultra-low-power battery monitoring in portable medical devices.

For engineers reviewing the TLV3404IDR datasheet, TLV3404IDR pinout, TLV3404IDR application, or TLV3404IDR equivalent, key selection criteria include quiescent current budget, input common-mode voltage headroom beyond VCC, open-drain output compatibility with mixed-voltage logic, and SOIC-14 package suitability for space-constrained industrial sensor nodes.

Technical Context

The TLV3404IDR implements a CMOS-input, open-drain output architecture optimized for nanopower operation without sacrificing input voltage range. Its input stage operates with –0.1 V to VCC + 5 V common-mode range, enabling high-side sensing above the supply rail - critical for battery voltage supervision and overvoltage detection circuits.

Each of its four independent comparators draws only 470 nA at 25°C and maintains functional operation down to 2.5 V supply, with propagation delays ranging from 30 µs (50 mV overdrive) to 300 µs (2 mV overdrive) under 10 pF load and 1 MΩ pull-up. Input bias current remains below 250 pA across temperature.

FAQ

What is the maximum input voltage allowed on TLV3404IDR pins relative to GND?

The TLV3404IDR supports an absolute maximum input voltage of VCC + 5 V or 20 V, whichever is lower, and can withstand –20 V on any input pin. This allows safe high-side sensing in 12 V systems and reverse-battery protection up to –18 V on VCC, making TLV3404IDR robust for automotive and portable equipment where supply polarity errors may occur.

Does TLV3404IDR require external pull-up resistors on its outputs?

Yes, TLV3404IDR has open-drain CMOS outputs and requires external pull-up resistors on all four output pins (1OUT, 2OUT, 3OUT, 4OUT) to define the logic HIGH level. A 1 MΩ pull-up is recommended per the datasheet to meet specified propagation delay and VOL performance; lower values reduce rise time but increase static current, while higher values degrade speed and noise immunity.

Can TLV3404IDR operate from a 2.5 V supply across the full industrial temperature range?

TLV3404IDR is specified for 2.5 V minimum supply voltage only at 0°C to +70°C (C-suffix). For the full –40°C to +125°C industrial range (I-suffix), the minimum operating supply is 2.7 V. Therefore, TLV3404IDR supports true 2.5 V operation only in commercial-grade applications; industrial-grade designs must use ≥2.7 V to guarantee functionality across temperature extremes.

What is the typical input offset voltage of TLV3404IDR and how does it affect accuracy?

The typical input offset voltage of TLV3404IDR is 250 µV at 25°C, with a maximum of 3.6 mV over the full industrial temperature range. This directly impacts threshold accuracy - for example, in a 1.25 V reference-based detector, the effective trip point may shift by ±3.6 mV, which is acceptable for battery end-of-discharge detection (e.g., 3.0 V ±10 mV) but requires calibration for sub-mV precision applications.

How does the supply current of TLV3404IDR vary with temperature and supply voltage?

TLV3404IDR supply current increases with temperature - from ~470 nA at 25°C to ~750 nA maximum across –40°C to +125°C - and is nearly constant across 2.5 V to 16 V supply. At 125°C, current rises to ~650 nA at 5 V and ~750 nA at 15 V. This predictable, monotonic behavior allows accurate lifetime estimation in battery-powered TLV3404IDR designs without complex derating models.
