Texas Instruments TLV3011AIDBVR

Overview

TLV3011AIDBVR 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 supply. It delivers 2–4 μs propagation delay and supports battery management systems requiring rail-to-rail sensing and stable reference accuracy.

For engineers reviewing the TLV3011AIDBVR datasheet, TLV3011AIDBVR pinout, TLV3011AIDBVR application, or TLV3011AIDBVR equivalent, key selection criteria include its open-drain output topology, built-in hysteresis (B-version), fail-safe inputs, power-on-reset functionality, and SOT-23-6 package compatibility with space-constrained portable electronics designs.

Technical Context

The TLV3011AIDBVR implements a precision comparator core with an uncommitted on-chip series voltage reference optimized for low drift (≤100 ppm/°C) and capacitive load stability up to 10 nF. Its input stage supports rail-to-rail common-mode operation with ±10 pA bias current and 60–74 dB CMRR.

This B-version device integrates power-on-reset (t_ON = 1.9 ms), fail-safe inputs that prevent undefined output during power ramp-up, and fixed internal hysteresis (2–8 mV) to suppress noise-induced oscillation-features absent in non-B variants.

FAQ

What is the function of the REF pin on the TLV3011AIDBVR?

The REF pin on the TLV3011AIDBVR provides a stable, factory-trimmed 1.242 V output with ±0.25% initial accuracy and ≤100 ppm/°C temperature drift. It can source or sink up to 0.5 mA and is internally decoupled for stability with up to 10 nF capacitive load. This eliminates the need for external reference components in threshold-detection circuits, reducing BOM count and PCB area in designs such as battery voltage monitors and toll tag wake-up comparators using TLV3011AIDBVR.

Does the TLV3011AIDBVR support operation below 1.8 V?

Yes, the TLV3011AIDBVR (B-version) is specified for operation from 1.65 V to 5.5 V, confirmed in Section 6.6 "Recommended Operating Conditions" and Section 6.9 "Electrical Characteristics" of the datasheet. This enables direct interface with single alkaline or lithium coin cells (1.5–3.0 V) and low-voltage microcontrollers without intermediate regulation-critical for multi-year battery life in asset tracking and wireless sensor nodes using TLV3011AIDBVR.

How does the fail-safe input feature work in the TLV3011AIDBVR?

The TLV3011AIDBVR's fail-safe inputs ensure the output remains in a known, non-floating state (logic high for open-drain) during power-up, brownout, or undervoltage conditions. This is implemented via internal biasing that overrides undefined input states until V+ and V− stabilize. Unlike standard comparators, this prevents spurious toggling or metastability in safety-critical applications such as automotive cluster display supervision or ADAS subsystems relying on TLV3011AIDBVR for rail monitoring.

Can the TLV3011AIDBVR drive an LED directly?

No, the TLV3011AIDBVR cannot drive an LED directly. Its open-drain OUT pin sinks up to 5 mA but lacks sourcing capability, and its VOL is 160–200 mV at 5 mA-insufficient to forward-bias most LEDs (typically requiring ≥1.6 V). To indicate comparator state, use an external pull-up to a higher voltage rail (e.g., 3.3 V or 5 V) and drive the LED through a series resistor from that node. This configuration is validated in typical application circuits for TLV3011AIDBVR in TI's SBOS300C datasheet.

What is the purpose of the built-in hysteresis in the TLV3011AIDBVR?

The built-in hysteresis (2–8 mV, depending on supply and temperature) in the TLV3011AIDBVR prevents output oscillation when the input signal is near the switching threshold in noisy environments. It creates distinct upper and lower trip points, eliminating the need for external positive-feedback resistors. This is especially valuable in applications like toll tag RF detection or battery cell monitoring using TLV3011AIDBVR, where EMI or sensor noise could otherwise cause repeated false triggers without additional filtering or layout effort.
