Texas Instruments TLV3011AIDBVTG4

Overview

TLV3011AIDBVTG4 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 delivers 4 μs typical propagation delay (low-to-high), ±0.25% reference accuracy, and operates across –40°C to +125°C - used in battery management systems for precise voltage threshold detection.

For engineers reviewing the TLV3011AIDBVTG4 datasheet, TLV3011AIDBVTG4 pinout, TLV3011AIDBVTG4 application, or TLV3011AIDBVTG4 equivalent, key selection criteria include ultra-low IQ, rail-to-rail input capability, built-in reference stability (100 ppm/°C max drift), fail-safe inputs, and power-on-reset functionality - all critical for space-constrained, single-supply industrial and automotive sensing nodes.

Technical Context

The TLV3011AIDBVTG4 implements a precision comparator core with an on-chip series voltage reference buffered to drive up to 0.5 mA load. Its B-version architecture includes internal hysteresis (2–8 mV), POR circuitry ensuring defined output state at power-up, and fail-safe input protection enabling operation even when inputs exceed supply rails by up to 7 V.

This device uses a CMOS input stage with 10¹³ Ω common-mode input impedance and supports open-drain output with external pull-up, enabling wired-OR logic and level translation. The reference output (REF pin) maintains ±0.25% initial accuracy and exhibits <1 mV/mA load regulation when sourcing up to 0.5 mA.

FAQ

What is the function of the REF pin on the TLV3011AIDBVTG4?

The REF pin on the TLV3011AIDBVTG4 provides a buffered, temperature-stable 1.242 V output with ±0.25% initial accuracy and ≤100 ppm/°C drift. It can source or sink up to 0.5 mA and serves as a precision reference for the comparator inputs or external circuitry - eliminating the need for an external voltage reference IC in battery voltage monitoring or threshold-detection applications using TLV3011AIDBVTG4.

Does the TLV3011AIDBVTG4 support operation below 1.8 V?

Yes, the TLV3011AIDBVTG4 is a "B-version" device rated for operation down to 1.65 V supply voltage, unlike the standard TLV3011 which requires ≥1.8 V. This enables direct use with single-cell LiFePO₄ (2.5–3.65 V) or alkaline batteries under depletion, while maintaining 3.1 μA maximum quiescent current and full functionality including POR and fail-safe inputs - a key specification confirmed for TLV3011AIDBVTG4 in its datasheet Section 6.6.

How does the fail-safe input feature work on the TLV3011AIDBVTG4?

The TLV3011AIDBVTG4 features fail-safe inputs that allow IN+ and IN− pins to tolerate voltages up to 7 V above V− (ground), even when V+ is unpowered or at low voltage. This is implemented via internal diode clamping and robust ESD structures. In battery management systems, this permits direct connection to unregulated battery strings without external attenuation - a verified behavior documented in Absolute Maximum Ratings (Section 6.2) and functional description for TLV3011AIDBVTG4.

Is the TLV3011AIDBVTG4 pin-compatible with other variants in the TLV3011 family?

Yes, TLV3011AIDBVTG4 uses the standard SOT-23-6 (DBV) package with identical pinout to TLV3011DBVR, TLV3011BIDBVT, and TLV3012BIDBVT - all share OUT/V−/IN+/IN−/REF/V+ assignment per Figure 5-1. However, functional differences exist: TLV3011AIDBVTG4 is open-drain and B-version (with POR/hysteresis), whereas TLV3012x variants have push-pull outputs. Pin compatibility is confirmed in TI's Mechanical, Packaging, and Orderable Information section.

What is the typical propagation delay of the TLV3011AIDBVTG4 at 1.8 V supply?

The TLV3011AIDBVTG4 exhibits 4 μs typical propagation delay (low-to-high) at 1.8 V supply, 100 mV input overdrive, and 10 pF load - per Table 6.10 (TPD-LH). This value increases slightly with temperature and decreases with higher supply voltage (e.g., 2 μs typical at 5 V). The delay is measured from input crossing to output crossing 50% of rail, and is validated across –40°C to +125°C in TI's characterization data for TLV3011AIDBVTG4.
