Product details
Overview
TLV3011BQDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified, open-drain output comparator with integrated 1.242V voltage reference, 3.1μA maximum quiescent current, 1.65V to 5.5V supply range, and fail-safe inputs. It serves as a precision voltage detection element in battery management systems and lane departure warning sensors where low power and robust input tolerance are critical.
For engineers reviewing the TLV3011BQDCKRQ1 datasheet, TLV3011BQDCKRQ1 pinout, TLV3011BQDCKRQ1 application, or TLV3011BQDCKRQ1 equivalent, this page delivers verified electrical specifications, SC-70 package layout, automotive-grade thermal and ESD performance data, and validated alternative options for fault-monitoring designs requiring rail-to-rail input operation and built-in hysteresis.
Technical Context
The TLV3011BQDCKRQ1 implements a rail-to-rail input comparator core with open-drain output stage and a dedicated 1.242V series voltage reference output (REF pin). Its fail-safe input architecture maintains high impedance up to 5.5V independent of V+ supply state, eliminating power sequencing constraints during cold-cranking or partial power-up conditions.
Internal power-on-reset (POR) asserts a known output state for 1.9ms during supply ramp-up or brownout, ensuring deterministic startup in safety-critical automotive subsystems. The 6mV typical hysteresis suppresses noise-induced chatter without external components, while the 200mV beyond-rails input common-mode range supports direct sensing of signals near supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables operation directly from single-cell LiFePO₄ or partially discharged 12V automotive rails. |
| Quiescent Current | 3.1μA max at TA = –40°C to +125°C - supports >10-year battery life in always-on asset tracking nodes. |
| Reference Voltage | 1.242V ±1.5% - provides stable threshold for precise overvoltage/undervoltage detection without external reference. |
| Input Common-Mode Range | (V–) – 0.2V to (V+) + 0.2V - allows direct monitoring of signals at or beyond supply rails (e.g., battery terminal sensing). |
| Hysteresis | 6mV typical - eliminates false triggering on noisy sensor outputs without adding external feedback resistors. |
| Propagation Delay | 2µs to 4µs (TPD-HL/TPD-LH, VOD = 100mV) - ensures rapid response to fault events in real-time safety systems. |
| ESD Rating | HBM ±2000V, CDM ±1000V - meets AEC-Q100 stress requirements for under-hood and infotainment environments. |
Pinout & Package
TLV3011BQDCKRQ1 is housed in a 6-pin SC-70 (DCK) package measuring 2.0mm × 2.1mm, optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Open-drain output | Sinks current only; requires external pull-up for logic-high state; supports wired-OR configurations across multiple comparators. |
| 2 - V– | Negative supply | Ground reference for both comparator and reference; accepts –0.2V to 5.5V common-mode input range relative to this node. |
| 3 - IN+ | Non-inverting input | Rail-to-rail capable; tolerates voltages up to 5.5V regardless of V+ level due to fail-safe input structure. |
| 4 - IN– | Inverting input | Rail-to-rail capable; same fail-safe voltage tolerance as IN+; differential input offset ≤ ±9mV over full temperature range. |
| 5 - REF | Reference output | Provides regulated 1.242V ±1.5%; stable with ≤10nF capacitive load; sources/sinks up to 0.5mA for external circuit biasing. |
| 6 - V+ | Positive supply | Accepts 1.65V to 5.5V; POR circuit activates below 1.65V and holds output in defined state for 1.9ms after crossing threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe inputs | IN+ and IN– tolerate 0V to 5.5V independent of V+ state - prevents latch-up or undefined output during supply transients. |
| Power-on-reset (POR) | 1.9ms guaranteed output hold time during V+ ramp-up/down - ensures deterministic startup in ASIL-B compliant systems. |
| Integrated 1.242V reference | ±1.5% initial accuracy, 100ppm/°C max drift - eliminates need for external reference IC or resistor divider in threshold detection. |
| Ultra-low IQ | 3.1μA max over –40°C to +125°C - enables continuous monitoring in energy-harvested or coin-cell-powered modules. |
| 200mV beyond-rails input range | Operates with inputs 200mV below V– or above V+ - supports direct sensing of battery voltage or sensor outputs near rail limits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3011BQDBVRQ1 | SOT-23-6 (DBV) package; 2.9mm × 2.8mm footprint; identical electrical specs and AEC-Q100 Grade 1 qualification. | Requires larger PCB area but offers higher thermal mass and easier hand-soldering; preferred for prototyping or high-vibration environments. | Select TLV3011BQDBVRQ1 when board space permits and mechanical robustness outweighs miniaturization needs. |
| TLV3012BQDCKRQ1 | Push-pull output instead of open-drain; same reference, IQ, supply range, and fail-safe/POR features. | Eliminates external pull-up resistor; suitable for driving CMOS inputs directly but cannot be wire-OR'd with other outputs. | Choose TLV3012BQDCKRQ1 when driving a single digital input without bus arbitration; avoid if multi-comparator wired-OR is required. |
Compared with TLV3011BQDCKRQ1, TLV3011BQDBVRQ1 trades board area for solderability and thermal margin, while TLV3012BQDCKRQ1 replaces open-drain flexibility with push-pull simplicity-both retain identical reference accuracy, fail-safe inputs, and automotive qualification.

FAQ
What is the minimum supply voltage for TLV3011BQDCKRQ1?
The TLV3011BQDCKRQ1 operates down to 1.65V, a key differentiator from non-"B" versions that require ≥1.8V. This lower limit enables reliable function during automotive cold-crank events where battery voltage dips below 2V. The internal POR circuit ensures defined output behavior throughout the 1.65V transition, making TLV3011BQDCKRQ1 suitable for direct connection to degraded 12V systems without external supervision.
Does TLV3011BQDCKRQ1 require external hysteresis for stable operation?
No, TLV3011BQDCKRQ1 includes 6mV typical internal hysteresis, sufficient for most automotive sensor interfaces with moderate noise. External hysteresis is optional and only needed for exceptionally noisy environments or when tighter switching thresholds are required. The datasheet confirms this value remains stable across –40°C to +125°C and varying supply voltages, eliminating calibration overhead in production.
How does the fail-safe input feature work in TLV3011BQDCKRQ1?
TLV3011BQDCKRQ1 inputs tolerate 0V to 5.5V regardless of V+ state - meaning they remain high-impedance and functional even when V+ is unpowered or ramping. This avoids false outputs during power sequencing mismatches. However, external clamping is required if input sources can exceed 5.5V, and current-limiting resistors are recommended for transient protection per TI's application guidance.
Can TLV3011BQDCKRQ1 drive a 10kΩ pull-up resistor reliably?
Yes, TLV3011BQDCKRQ1's open-drain output sinks ≥5mA at VOL ≤200mV (TA = –40°C to +125°C), easily supporting standard 10kΩ pull-ups to 3.3V or 5V. Its ability to sink current up to 5.5V - independent of V+ - allows flexible interfacing with higher-voltage logic families. Output fall time remains ≤200ns under these conditions, preserving timing integrity in fast-response systems.
Is the 1.242V reference in TLV3011BQDCKRQ1 buffered and load-tolerant?
Yes, the REF pin delivers 1.242V ±1.5% with ≤100ppm/°C drift and remains stable with up to 10nF capacitive load. It sources/sinks up to 0.5mA while maintaining accuracy, enabling direct use for biasing external op-amps or ADC references. Load regulation is specified at 1mV/mA (sourcing) and 6.6mV/mA (sinking), confirming robustness across typical sensor interface loads.
