Texas Instruments TLV3404IPWRG4

Overview

TLV3404IPWRG4 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 features 250 µV typical input offset voltage, 55–88 dB CMRR, and 5 µs typical fall time - enabling ultra-low-power threshold detection in battery-constrained systems such as portable medical sensors and wireless security nodes.

For engineers reviewing the TLV3404IPWRG4 datasheet, TLV3404IPWRG4 pinout, TLV3404IPWRG4 application, or TLV3404IPWRG4 equivalent, key selection criteria include its nanopower consumption, extended common-mode input beyond VCC, open-drain output compatibility with mixed-voltage logic, and industrial-grade temperature support (–40°C to +125°C) in TSSOP-14 packaging.

Technical Context

The TLV3404IPWRG4 implements a precision comparator core with differential input stage optimized for sub-µA quiescent operation. Its input stage supports common-mode voltages up to 5 V above VCC without damage, enabling high-side sensing in systems with reverse-battery protection requirements.

Each of the four independent channels uses an open-drain CMOS output stage requiring external pull-up, with low-level output voltage specified at 8 mV (IOL = 2 µA) and leakage current ≤50 pA at 25°C - ensuring reliable interfacing with 1.8 V, 3.3 V, or 5 V digital logic while minimizing standby power.

FAQ

What is the maximum input voltage allowed on TLV3404IPWRG4 inputs?

The TLV3404IPWRG4 supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum input voltage limited to 20 V or VCC + 5 V (whichever is smaller). This allows safe high-side sensing - for example, monitoring a 12 V battery with 5 V supply - without external clamping diodes. Exceeding these limits risks permanent damage per Absolute Maximum Ratings.

Does TLV3404IPWRG4 require external pull-up resistors on its outputs?

Yes, TLV3404IPWRG4 has open-drain CMOS outputs and requires external pull-up resistors to define the logic HIGH state. The datasheet specifies performance with a 1 MΩ pull-up; values between 10 kΩ and 10 MΩ are usable depending on speed vs. power trade-offs. Lower resistance improves rise time but increases static current; higher resistance reduces power but slows response - especially with capacitive loads.

What is the operating temperature range for TLV3404IPWRG4?

The TLV3404IPWRG4 is rated for industrial operation from –40°C to +125°C, verified across all electrical parameters including supply current, input offset voltage, and propagation delay. This range is confirmed in the Recommended Operating Conditions table and supported by thermal metrics (RθJA = 120.8°C/W for TSSOP-14), making it suitable for under-hood automotive, industrial control, and outdoor IoT applications.

Can TLV3404IPWRG4 be used with a 2.5 V supply?

Yes, TLV3404IPWRG4 is fully specified down to 2.5 V single supply (or ±1.25 V dual supply) across the full industrial temperature range. At 2.5 V, it maintains 470 nA typical supply current per channel and retains input common-mode range down to –0.1 V, enabling use in low-voltage energy-harvesting systems powered by harvested RF or thermal sources.

How does TLV3404IPWRG4 handle reverse battery connection?

TLV3404IPWRG4 includes reverse battery protection: it withstands –18 V applied to VCC relative to GND without damage or excessive current draw. This protects the device during improper battery installation in consumer or medical devices. The specification is validated per Absolute Maximum Ratings and applies regardless of input or output states - no external protection circuitry is needed.
