Texas Instruments TLV3011AIDCKR

Overview

TLV3011AIDCKR from Texas Instruments is a low-power, open-drain output comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (B-version), input common-mode range extending 200 mV beyond rails, and operation from 1.65 V to 5.5 V. It serves as a precision threshold detector in battery-constrained systems such as toll tags and asset trackers.

For engineers reviewing the TLV3011AIDCKR datasheet, TLV3011AIDCKR pinout, TLV3011AIDCKR application, or TLV3011AIDCKR equivalent, key selection criteria include its open-drain output architecture, built-in reference accuracy (±0.25% typical), fail-safe inputs, power-on-reset functionality, and SC-70-6 package suitability for space-constrained PCB layouts.

Technical Context

The TLV3011AIDCKR implements a rail-to-rail input comparator core paired with a buffered series voltage reference, enabling direct sensing of signals near supply rails without external biasing. Its internal hysteresis (2–8 mV) suppresses noise-induced oscillation during slow-moving input transitions.

Power-on-reset ensures deterministic output state at power-up, while fail-safe inputs guarantee valid logic levels even when input voltages exceed supply rails by up to 0.5 V - critical for robustness in automotive and industrial sensor interfaces.

FAQ

What is the reference voltage accuracy of TLV3011AIDCKR over temperature?

The TLV3011AIDCKR reference voltage has an initial accuracy of ±0.25% at 25°C and maintains ±1.5% accuracy over the full −40°C to +125°C operating range, as specified in Section 6.9 of the SBOS300C datasheet. This ensures reliable threshold detection without recalibration across environmental extremes.

Does TLV3011AIDCKR support operation below 1.8 V supply?

Yes - the TLV3011AIDCKR (B-version) is rated for operation from 1.65 V to 5.5 V, confirmed in Section 6.6 Recommended Operating Conditions. This enables use with single-cell alkaline, NiMH, or low-voltage Li-ion batteries where headroom is constrained.

How does the fail-safe input feature work in TLV3011AIDCKR?

The fail-safe inputs in TLV3011AIDCKR guarantee valid logic output even when IN+ or IN− voltages fall below V− or exceed V+ by up to 0.5 V, per Section 6.2 Absolute Maximum Ratings. This prevents undefined output states during sensor fault conditions or power sequencing mismatches.

Can TLV3011AIDCKR drive capacitive loads directly?

Yes - the integrated reference output is stable with up to 10 nF capacitive load (Section 3 Description), and the comparator output drives CL = 10 pF with 10 ns rise/fall times (Section 6.10). For larger loads, external buffering is recommended to maintain propagation delay integrity.

Is TLV3011AIDCKR pin-compatible with non-B versions like TLV3011IDCKR?

No - TLV3011AIDCKR (B-version) includes power-on-reset, fail-safe inputs, and hysteresis not present in standard TLV3011IDCKR. While pinout and package are identical, functional differences require schematic and firmware review before substitution.
