Texas Instruments TLV3401IDBVR

Overview

TLV3401IDBVR 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 supply. It delivers rail-to-rail input capability and reverse battery protection up to 18 V, making it ideal for ultra-low-power battery monitoring in portable medical devices.

For engineers reviewing the TLV3401IDBVR datasheet, TLV3401IDBVR pinout, TLV3401IDBVR application, or TLV3401IDBVR equivalent, key selection criteria include quiescent current budget, input overvoltage tolerance, open-drain output drive requirements, and SOT-23 thermal performance in space-constrained designs.

Technical Context

The TLV3401IDBVR implements a precision comparator core with input stage biasing enabling operation down to 2.5 V while maintaining 250 µV typical input offset voltage and 55–88 dB CMRR across supply voltages. Its open-drain CMOS output requires external pull-up and supports logic-level interfacing with microcontrollers or FPGAs.

Designed for harsh environments, the device tolerates input voltages up to VCC + 5 V (max 20 V) without damage and includes reverse-battery protection to prevent destructive current flow during incorrect battery insertion - critical for field-deployed handheld instruments.

FAQ

What is the maximum input voltage allowed on TLV3401IDBVR pins?

The TLV3401IDBVR allows input voltages from –0.1 V to VCC + 5 V, with an absolute maximum of 20 V (whichever is smaller). This means at VCC = 5 V, inputs may safely reach 10 V - enabling direct high-side sensing without external attenuators or clamps. Exceeding these limits risks permanent damage.

Does TLV3401IDBVR require an external pull-up resistor on its output?

Yes, TLV3401IDBVR features an open-drain CMOS output and requires an external pull-up resistor to function. The datasheet specifies performance with a 1-MΩ pull-up to VCC; lower values improve rise time but increase static power, while higher values degrade switching speed and noise immunity. TLV3401IDBVR cannot drive logic-high without this resistor.

Can TLV3401IDBVR operate from a 2.5-V supply across the full industrial temperature range?

TLV3401IDBVR is rated for 2.5 V minimum supply voltage only for commercial-grade (0°C to +70°C) operation. For the full –40°C to +125°C industrial range, the minimum supply is 2.7 V per TI's recommended operating conditions. Using 2.5 V at –40°C may result in undefined behavior or failure to meet propagation delay or offset specs.

What is the typical input bias current of TLV3401IDBVR and how does it affect threshold accuracy?

TLV3401IDBVR has a typical input bias current of 80 pA at 25°C, rising to 1500 pA over full temperature range. When used with high-impedance resistor dividers (e.g., 1 MΩ), this current introduces <1 mV error in threshold setting - negligible for most 10-mV–level detection tasks. For sub-millivolt accuracy, lower divider impedances or input buffering are advised.

Is TLV3401IDBVR pin-compatible with other members of the TLV340x family?

No - TLV3401IDBVR (5-pin SOT-23) is not pin-compatible with TLV3402 (8-pin MSOP/SOIC) or TLV3404 (14-pin TSSOP/SOIC/PDIP). Each variant has distinct pin counts, functions, and layouts. Substituting between them requires PCB redesign. TLV3401IDBVR shares footprint only with other 5-pin SOT-23 comparators like TLV3701IDBVR, but functional differences remain.
