Product details
Overview
TLV3011AQDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade, open-drain output comparator with integrated 1.242 V voltage reference, 3.1 µA maximum quiescent current (B-version), 6 mV typical built-in hysteresis, and rail-to-rail input common-mode range extending 200 mV beyond supply rails. It operates from 1.65 V to 5.5 V and is used in battery management systems for precise low-power voltage threshold detection.
For engineers reviewing the TLV3011AQDCKRQ1 datasheet, TLV3011AQDCKRQ1 pinout, TLV3011AQDCKRQ1 application, or TLV3011AQDCKRQ1 equivalent, this page delivers verified electrical specs, automotive-qualified thermal and ESD performance, SC-70 package layout guidance, and direct alternatives for fault-monitoring designs requiring fail-safe inputs and power-on-reset behavior.
Technical Context
The TLV3011AQDCKRQ1 implements a rail-to-rail input comparator core with open-drain output stage and a separate buffered 1.242 V series reference output (REF pin). Its internal hysteresis (6 mV typ.) stabilizes switching against noise without external components.
As a B-version device, it features fail-safe inputs rated to 5.5 V independent of V+ supply, power-on-reset (1.9 ms active period), and guaranteed operation down to 1.65 V supply - enabling robust voltage monitoring during cold-crank or brownout conditions in automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports automotive cold-crank (≥1.65 V) and full-battery-range operation without external regulators |
| Quiescent Current | 3.1 µA max at TA = –40°C to +125°C - enables multi-year battery life in always-on vehicle tracking or toll tag applications |
| Reference Voltage | 1.242 V ±1.5% initial accuracy - provides stable, factory-trimmed threshold for precision undervoltage/overvoltage detection |
| Input Common-Mode Range | (V–) – 0.2 V to (V+) + 0.2 V - allows direct sensing of signals beyond supply rails (e.g., battery voltage above V+) |
| Hysteresis | 6 mV typical - suppresses chatter on noisy analog inputs without requiring external feedback resistors |
| Propagation Delay | 2 µs to 4 µs (TPD-HL/TPD-LH, VOD = 100 mV) - ensures fast response to critical fault events like cell overvoltage in BMS |
| ESD Rating | HBM ±2000 V, CDM ±1000 V - meets AEC-Q100-002/-011 requirements for automotive PCB handling and system integration |
Pinout & Package
TLV3011AQDCKRQ1 is housed in a 6-pin SC-70 (DCK) package measuring 2.0 mm × 2.1 mm, optimized for space-constrained automotive modules such as body control units and sensor nodes.
| 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 fault-bus architectures |
| 2 - V– | Negative supply terminal | Connects to system ground or lowest potential rail; serves as reference for all input/output voltage ranges |
| 3 - IN+ | Non-inverting input | Compares sensed signal (e.g., battery voltage divider) against reference or other input; rail-to-rail capable |
| 4 - IN– | Inverting input | Accepts reference voltage (e.g., 1.242 V from REF) or threshold-setting signal; failsafe up to 5.5 V |
| 5 - REF | Reference output | Provides regulated 1.242 V ±1.5%; sources/sinks up to 0.5 mA; stable with ≤10 nF capacitive load |
| 6 - V+ | Positive supply terminal | Accepts 1.65–5.5 V supply; powers comparator core and reference; POR circuit triggers below 1.65 V |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe inputs | IN+ and IN– tolerate 0 V to 5.5 V regardless of V+ state - eliminates power-sequencing constraints in multi-rail systems |
| Power-on-reset (POR) | 1.9 ms output hold period during V+ ramp-up/down - ensures known output state and stable REF before decision-making |
| Integrated 1.242 V reference | 100 ppm/°C max drift, ±1.5% initial accuracy - removes need for external precision reference IC or resistor divider |
| Ultra-low IQ | 3.1 µA max across –40°C to +125°C - reduces self-heating and extends battery runtime in always-on monitoring circuits |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C), HBM ±2 kV, CDM ±1 kV - validated for under-hood and cabin ECU deployment |

FAQ
What is the supply voltage range for TLV3011AQDCKRQ1?
The TLV3011AQDCKRQ1 operates from 1.65 V to 5.5 V. This extended low-voltage limit supports automotive cold-crank conditions and enables direct use with single-cell Li-ion or supercapacitor supplies. Operation outside this range may cause undefined behavior or damage, per absolute maximum ratings.
Does TLV3011AQDCKRQ1 include an integrated voltage reference?
Yes, TLV3011AQDCKRQ1 integrates a precision 1.242 V series voltage reference accessible on the REF pin. It delivers ±1.5% initial accuracy, 100 ppm/°C max temperature drift, and can source/sink up to 0.5 mA - eliminating the need for external reference components in threshold-detection circuits.
How does the power-on-reset (POR) function in TLV3011AQDCKRQ1?
TLV3011AQDCKRQ1 incorporates a POR circuit that holds the open-drain output in high-impedance (Hi-Z) state for 1.9 ms during V+ ramp-up or ramp-down. This ensures the reference output stabilizes before comparator decisions begin, preventing spurious outputs during power transitions.
What are the key differences between TLV3011AQDCKRQ1 and TLV3012BQDCKRQ1?
TLV3011AQDCKRQ1 has an open-drain output, while TLV3012BQDCKRQ1 uses a push-pull output. Both share identical reference, quiescent current, fail-safe inputs, and POR. The open-drain version supports wired-OR fault buses; the push-pull version eliminates pull-up resistors and offers faster rise times.
Is TLV3011AQDCKRQ1 qualified for automotive applications?
Yes, TLV3011AQDCKRQ1 is AEC-Q100 qualified for Grade 1 (–40°C to +125°C ambient), with HBM ±2000 V and CDM ±1000 V ESD ratings. It is designed and tested for deployment in engine control units, body electronics, and ADAS modules where reliability under harsh environmental stress is mandatory.
