Texas Instruments TLV3011BIDBVR

Overview

TLV3011BIDBVR from Texas Instruments is a low-power, open-drain comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current, 2–4 μs propagation delay (low-to-high/high-to-low), and fail-safe inputs - designed for battery-critical applications such as toll tags and asset tracking.

For engineers reviewing the TLV3011BIDBVR datasheet, TLV3011BIDBVR pinout, TLV3011BIDBVR application, or TLV3011BIDBVR equivalent, key selection criteria include supply voltage range (1.65 V to 5.5 V), built-in hysteresis (2–8 mV), power-on-reset functionality, input common-mode range extending 200 mV beyond rails, and SOT-23-6 package compatibility.

Technical Context

The TLV3011BIDBVR implements a rail-to-rail input comparator core with an on-chip series voltage reference, enabling self-contained threshold detection without external reference components. Its fail-safe input architecture ensures defined output states during undervoltage or floating-input conditions.

Power-on-reset (POR) asserts a known output state during power ramp-up, while integrated hysteresis eliminates oscillation near switching thresholds. The open-drain output supports wired-OR logic and flexible pull-up voltage selection up to 7 V relative to V–.

FAQ

What is the minimum operating supply voltage for TLV3011BIDBVR?

The TLV3011BIDBVR operates down to 1.65 V, enabling compatibility with partially discharged lithium-based batteries and low-voltage microcontroller domains. This is a key differentiator from the non-"B" TLV3011 variant, which requires ≥1.8 V. Operation at 1.65 V is fully specified across –40°C to +125°C.

Does TLV3011BIDBVR require external hysteresis components?

No - TLV3011BIDBVR integrates 2–8 mV of hysteresis internally, eliminating the need for external feedback resistors. This hysteresis is inherent to the "B" version and is temperature- and supply-dependent, as documented in Section 6.9 of the datasheet. It stabilizes switching behavior in noisy environments without design overhead.

How does the fail-safe input feature work on TLV3011BIDBVR?

The TLV3011BIDBVR's IN– pin is fail-safe: if its voltage falls below (V–) – 0.3 V (e.g., due to open circuit or ESD damage), the output is forced high. This prevents indeterminate states in sensor-fault scenarios - a critical safety feature in automotive and industrial monitoring where missing signals must trigger alarms, not silence.

Can the REF pin of TLV3011BIDBVR drive external circuitry?

Yes - the REF pin delivers a stable 1.242 V ±0.25% with up to 0.5 mA sourcing/sinking capability and ≤10 nF capacitive load stability. It can directly bias sensors, set ADC reference points, or feed secondary comparators. Load regulation is specified at 0.36–6.6 mV/mA depending on direction, supporting moderate-current analog front-ends.

Is TLV3011BIDBVR pin-compatible with TLV3011IDBVR?

Yes - TLV3011BIDBVR and TLV3011IDBVR share identical SOT-23-6 pinout, footprint, and terminal functions. However, the "B" version adds POR, fail-safe inputs, hysteresis, and lower minimum supply (1.65 V vs. 1.8 V). Swapping requires verifying that system-level timing and fault-response requirements align with the enhanced "B" functionality.
