Product details
Overview
TLV3401ID from Texas Instruments is a single-channel nanopower comparator with open-drain CMOS output, designed for ultra-low-power sensing and threshold detection in battery-critical systems. It operates from 2.5 V to 16 V, draws only 470 nA supply current per channel at 25°C, supports input common-mode voltage from –0.1 V to VCC + 5 V, and is rated for industrial temperature range (–40°C to +125°C). It is used in portable medical devices and wireless security sensors where quiescent current and rail-exceeding input range are essential.
For engineers reviewing the TLV3401ID datasheet, TLV3401ID pinout, TLV3401ID application, or TLV3401ID equivalent, key selection criteria include its 470 nA supply current, –0.1 V to VCC + 5 V input common-mode range, open-drain output requiring external pull-up, 5-pin SOT-23 package, and industrial-grade temperature rating - all critical for energy-constrained, high-reliability analog monitoring designs.
Technical Context
The TLV3401ID implements a precision comparator core with rail-to-rail input stage enabling operation beyond VCC, supporting high-side voltage sense and reverse-battery-protected configurations. Its open-drain output interface requires an external pull-up resistor (typically 1 MΩ) to define logic-high level and control rise time.
It features reverse-battery protection up to 18 V, ESD ratings of ±2000 V HBM and ±1500 V CDM, and maintains stable performance across –40°C to +125°C with input offset voltage of 250 µV (typ), 4400 µV (max over full range), and 3 µV/°C drift - making it suitable for unregulated or wide-voltage-supply environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 470 nA per channel at 25°C - enables multi-year battery life in coin-cell-powered sensors |
| Supply Voltage Range | 2.5 V to 16 V single supply - supports direct connection to Li-ion, 9 V batteries, or 12 V industrial rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3401IPW | Same electrical specs; packaged in 5-pin TSSOP (PW) with 2.00 mm × 1.25 mm footprint - larger pad pitch eases hand-soldering but increases board area | Suitable for prototyping or low-volume production where reflow capability is limited | Select TLV3401IPW when manual assembly or thermal relief requirements favor TSSOP over SOT-23 |
| TLV7011DBVR | Lower supply current (350 nA), wider supply range (1.4–6.5 V), but no reverse-battery protection and narrower input range (to VCC + 0.2 V) | Better for single-cell LiFePO₄ or 3.3 V systems; unsuitable for 9 V battery or high-side sensing above VCC | Choose TLV7011DBVR only if operating strictly within 1.4–6.5 V and reverse-protection is not required |
Compared with TLV3401IPW and TLV7011DBVR, the TLV3401ID uniquely combines 470 nA supply current, VCC + 5 V input tolerance, and –40°C to +125°C rating in the smallest 5-pin SOT-23 package - making it the only option for miniaturized, wide-supply, industrial-grade threshold detection.

FAQ
What is the maximum supply voltage the TLV3401ID can withstand without damage?
The TLV3401ID has an absolute maximum supply voltage rating of 17 V. Exceeding this value may cause permanent damage. For reliable operation, TI specifies a recommended maximum of 16 V under normal conditions. The device also includes reverse-battery protection up to –18 V on the VCC pin, safeguarding against incorrect battery installation in field-deployed TLV3401ID-based systems.
Does the TLV3401ID support rail-to-rail input operation?
The TLV3401ID does not support true rail-to-rail input - instead, it offers an extended input common-mode range from –0.1 V to VCC + 5 V. This means both inputs can operate 0.1 V below ground and up to 5 V above VCC, enabling high-side sensing and robustness against overvoltage transients. This behavior differs from standard rail-to-rail input op-amps and is explicitly documented in the TLV3401ID datasheet Section 7.3.
What pull-up resistor value is recommended for the TLV3401ID open-drain output?
Texas Instruments fully specifies the TLV3401ID with a 1 MΩ pull-up resistor to VCC. This value balances output voltage swing, power consumption, and propagation delay - delivering VOL ≤ 80 mV at IOL = 50 µA while keeping leakage negligible. Using smaller values (e.g., 10 kΩ) increases power draw and heat; larger values (>10 MΩ) degrade rise time and noise immunity. The 1 MΩ value is validated across –40°C to +125°C for the TLV3401ID.
Can the TLV3401ID be used with a 1.8 V supply?
No, the TLV3401ID cannot be operated reliably at 1.8 V. Its minimum recommended supply voltage is 2.5 V for C-suffix versions and 2.7 V for I-suffix versions (including TLV3401ID). At 1.8 V, the internal biasing fails, resulting in undefined output states, excessive propagation delay, and potential failure to meet input common-mode or offset specifications. For 1.8 V systems, consider alternatives such as TLV7011 or TLV3601.
Is the TLV3401ID pin-compatible with other members of the TLV340x family?
No, the TLV3401ID is not pin-compatible with TLV3402 or TLV3404. As a single-channel device in 5-pin SOT-23, it has unique pin mapping (OUT, GND, IN+, IN–, VCC). Dual-channel TLV3402 uses 8-pin SOIC/VSSOP packages with different pin assignments, and quad TLV3404 uses 14-pin packages. Substituting across TLV340x variants requires PCB layout changes and signal routing updates - TLV3401ID's compact 5-pin footprint is exclusive to the single-channel configuration.
