Texas Instruments TLV3011AIDBVRG4

Overview

TLV3011AIDBVRG4 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 tracking devices.

For engineers reviewing the TLV3011AIDBVRG4 datasheet, TLV3011AIDBVRG4 pinout, TLV3011AIDBVRG4 application, or TLV3011AIDBVRG4 equivalent, key selection criteria include its guaranteed 2–4 μs propagation delay (low-to-high/high-to-low), ±0.25% reference accuracy, fail-safe inputs, power-on-reset functionality, and validated performance across –40°C to +125°C.

Technical Context

The TLV3011AIDBVRG4 implements a rail-to-rail input comparator core with an uncommitted on-chip series voltage reference, enabling direct use without external reference components. Its B-version architecture integrates hysteresis (2–8 mV), POR, and fail-safe inputs that prevent undefined output states during power ramp-up or input overvoltage conditions.

It operates with single-supply biasing (V+ and V− pins), supports open-drain output interfacing with external pull-up networks, and delivers stable reference output capable of sourcing/sinking up to 0.5 mA while maintaining ≤100 ppm/°C drift and ≤1 mV/mA load regulation.

FAQ

What is the reference voltage accuracy specification for TLV3011AIDBVRG4?

The TLV3011AIDBVRG4 has a reference voltage accuracy of ±0.25% at 25°C, with initial tolerance tightened versus non-B versions. This is confirmed in Section 6.9 of the SBOS300C datasheet under "Voltage Reference" specifications, where VOUT is specified as 1.223 V to 1.260 V at TA = 25°C. The ±0.25% value reflects tighter binning applied to the "B" variant, enabling high-precision threshold detection without external calibration.

Does TLV3011AIDBVRG4 support operation below 1.8 V?

Yes, TLV3011AIDBVRG4 supports operation down to 1.65 V, as explicitly stated in Section 6.6 ("Recommended Operating Conditions") and Section 6.9 ("Electrical Characteristics - TLV3011B and TLV3012B"). This extended low-voltage capability distinguishes it from the standard TLV3011/TLV3012 (1.8 V min) and enables direct use with single-cell LiFePO₄ or alkaline batteries nearing end-of-life.

What does "fail-safe inputs" mean for TLV3011AIDBVRG4?

"Fail-safe inputs" in TLV3011AIDBVRG4 means the device guarantees a known output state (high-impedance or logic-low depending on configuration) when either input is driven beyond the absolute maximum ratings or left floating during power-up. This behavior is implemented via internal clamping and biasing circuitry, preventing indeterminate output states - a requirement for ASIL-B–compatible subsystems in automotive clusters and toll tags per ISO 26262 functional safety guidelines.

Is TLV3011AIDBVRG4 pin-compatible with TLV3011DBVR?

Yes, TLV3011AIDBVRG4 is pin-compatible with TLV3011DBVR: both use the SOT-23-6 (DBV) package with identical pinout (OUT, V−, IN+, IN−, REF, V+). However, TLV3011AIDBVRG4 includes "B"-version enhancements (POR, hysteresis, fail-safe inputs) not present in TLV3011DBVR, so firmware or system-level timing assumptions must be verified when substituting.

What is the maximum capacitive load the REF pin can drive in TLV3011AIDBVRG4?

The REF pin of TLV3011AIDBVRG4 is stable with up to 10 nF capacitive load, as documented in the "Description" section of the SBOS300C datasheet. This allows direct decoupling with ceramic capacitors for noise suppression without risk of oscillation, supporting clean reference delivery to ADCs, DACs, or other comparators sharing the same reference node.
