Texas Instruments TLV3401IDBVTG4

Overview

TLV3401IDBVTG4 from Texas Instruments is a single-channel nanopower open-drain comparator with 470 nA supply current, –0.1 V to VCC + 5 V input common-mode range, and operation from 2.5 V to 16 V. It delivers rail-to-rail input capability and reverse battery protection up to 18 V, enabling use in ultra-low-power battery monitoring circuits for portable medical devices.

For engineers reviewing the TLV3401IDBVTG4 datasheet, TLV3401IDBVTG4 pinout, TLV3401IDBVTG4 application, or TLV3401IDBVTG4 equivalent, key selection criteria include quiescent current budget, input voltage headroom beyond VCC, open-drain output compatibility with external pull-up networks, and industrial temperature support (–40°C to +125°C).

Technical Context

The TLV3401IDBVTG4 implements a precision comparator core with input offset voltage of 250 µV (typ), CMRR of 55–88 dB across supply voltages, and differential input resistance of 300 MΩ. Its open-drain CMOS output stage requires an external pull-up resistor and supports logic-level interfacing with microcontrollers or FPGAs.

It operates over a wide supply range (2.5 V to 16 V) and features reverse battery protection up to 18 V, allowing safe deployment in harsh environments where supply polarity reversal may occur. Input bias current remains below 250 pA (max) at 25°C, supporting high-impedance sensing applications without loading source signals.

FAQ

What is the maximum input voltage allowed on the TLV3401IDBVTG4 inputs?

The TLV3401IDBVTG4 supports an input common-mode range from –0.1 V to VCC + 5 V, with absolute maximum input voltage limited to the smaller of 20 V or VCC + 5 V. For example, at VCC = 5 V, inputs may safely reach up to 10 V. This specification is confirmed in Section 7.1 Absolute Maximum Ratings and Section 7.3 Recommended Operating Conditions of the SLCS135B datasheet.

Does TLV3401IDBVTG4 have rail-to-rail output capability?

No, the TLV3401IDBVTG4 features an open-drain CMOS output stage, not rail-to-rail output. Its output can only actively drive low (down to 8 mV typical at 2 µA sink) and floats high when inactive. A pull-up resistor to VCC or another logic rail is mandatory to establish a defined HIGH state - this architecture enables wired-OR logic and level translation, as documented in Section 6 Pin Configuration and Functions.

What is the operating temperature range for TLV3401IDBVTG4?

The TLV3401IDBVTG4 is an industrial-grade device rated for operation from –40°C to +125°C, as specified in Section 7.3 Recommended Operating Conditions and confirmed by thermal characterization data in Section 7.4. This range applies across the full 2.7 V to 16 V supply range and is validated for both electrical performance and reliability.

Can TLV3401IDBVTG4 be used with a dual supply?

Yes, the TLV3401IDBVTG4 supports dual-supply operation from ±1.25 V to ±8 V, as stated in Section 8.3.1 Operating Voltage and Section 7.3 Recommended Operating Conditions. When using dual supplies, the GND pin serves as the reference midpoint, and input common-mode range extends from –0.1 V to V_CC + 5 V relative to GND - enabling symmetric or asymmetric split-rail configurations.

Is TLV3401IDBVTG4 pin-compatible with other TLV340x variants?

The TLV3401IDBVTG4 (SOT-23-5) is not pin-compatible with TLV3402 or TLV3404 due to differing channel counts and package footprints. However, within the TLV3401 family, all SOT-23-5 versions - including TLV3401IDBVTG4, TLV3401DBVR, and TLV3401DBVT - share identical pinout, function mapping, and mechanical dimensions, as verified in Section 6 Pin Configuration and Functions of the datasheet.
