Product details
Overview
TLV3401IDBVT 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 rail-to-rail input common-mode range (–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 dominates system lifetime.
For engineers reviewing the TLV3401IDBVT datasheet, TLV3401IDBVT pinout, TLV3401IDBVT application, or TLV3401IDBVT equivalent, key selection criteria include sub-µA supply current, reverse-battery protection up to 18 V, open-drain output compatibility with mixed-voltage logic, and SOT-23-5 package suitability for space-constrained PCB layouts.
Technical Context
The TLV3401IDBVT implements a precision comparator core with input offset voltage of 250 µV (typ) and 4400 µV (max) over full temperature range, enabling accurate low-level signal discrimination. Its differential input resistance exceeds 300 MΩ and input bias current is as low as 80 pA (typ), minimizing loading on high-impedance sensor sources like thermistors or photodiodes.
Propagation delay is overdrive-dependent: 55 µs (low-to-high) and 30 µs (high-to-low) at 50 mV overdrive with 10 pF load and 1 MΩ pull-up; fall time is 5 µs. The device features reverse-battery protection and withstands input voltages up to VCC + 5 V without damage - critical for automotive and industrial field-sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3401IDCKR | SOT-23-5 package with same electrical specs; differs only in tape-and-reel packaging (DBVT = 250-unit reel, DCKR = 3000-unit reel) | No functional difference; selected for high-volume automated assembly vs. prototyping or low-volume production | Choose TLV3401IDCKR for SMT line efficiency; TLV3401IDBVT for evaluation or small-batch builds |
| TLV7011DBVR | Lower supply current (350 nA typ), but narrower supply range (1.4–6 V); no reverse-battery protection; same SOT-23-5 footprint | Better suited for single-cell Li-ion or 3.3 V systems; unsuitable for 12 V industrial or reverse-polarity environments | Use TLV7011DBVR only if supply is strictly ≤6 V and reverse-battery risk is absent |
Compared with TLV3401IDBVT, TLV3401IDCKR offers identical performance in higher-volume packaging, while TLV7011DBVR trades industrial voltage range and reverse-battery robustness for lower quiescent current - making TLV3401IDBVT the sole choice for 12 V field-deployed or polarity-uncontrolled applications.

FAQ
What is the maximum input voltage the TLV3401IDBVT can tolerate relative to its supply rail?
The TLV3401IDBVT supports an input common-mode voltage range from –0.1 V to VCC + 5 V. This means its inputs can safely accept signals up to 5 V above the positive supply rail - for example, 10 V when VCC = 5 V - without damage. This feature enables direct high-side sensing in applications like battery voltage monitoring or industrial sensor front-ends where signals exceed the supply voltage. Absolute maximum input is limited to 20 V or VCC + 5 V, whichever is smaller.
Does the TLV3401IDBVT require external pull-up resistors on its output?
Yes, the TLV3401IDBVT has an open-drain CMOS output and requires an external pull-up resistor to establish a defined high logic level. TI specifies performance with a 1-MΩ pull-up to VCC; values between 10 kΩ and 10 MΩ are usable depending on speed and power trade-offs. Lower resistance improves rise time but increases static current; higher resistance reduces power but slows response. The TLV3401IDBVT itself does not source current on the output line.
What is the operating temperature range certified for the TLV3401IDBVT?
The TLV3401IDBVT is rated for the industrial temperature range of –40°C to +125°C. This is confirmed by its "I" suffix designation and validated across all electrical specifications in the datasheet, including supply current, input offset voltage, and propagation delay. It is not rated for extended automotive AEC-Q100 qualification, but its thermal performance (RθJA = 237.8°C/W) and reverse-battery protection make it suitable for under-hood and factory-floor deployments.
Can the TLV3401IDBVT be used with a 1.8-V logic interface?
Yes, the TLV3401IDBVT's open-drain output allows direct interface to 1.8-V logic systems. By connecting the external pull-up resistor to a 1.8-V rail instead of VCC, the output high level becomes 1.8 V, fully compatible with 1.8-V GPIOs. Input common-mode range remains valid down to 2.5 V supply, so the device can operate from a higher VCC (e.g., 3.3 V or 5 V) while driving a 1.8-V domain - a common requirement in mixed-voltage IoT sensor nodes.
How does reverse-battery protection work in the TLV3401IDBVT?
The TLV3401IDBVT incorporates internal circuitry that blocks excessive current flow when VCC is reversed (e.g., –18 V applied), preventing latch-up or permanent damage. This protection is inherent to the IC's input stage design and requires no external components. It is validated per absolute maximum ratings and enables safe use in consumer or industrial products where end users may incorrectly install batteries - a critical reliability feature for field-deployed equipment like smoke detectors or remote sensors.
