Product details
Overview
TLV3012AQDCKRQ1 from Texas Instruments is an automotive-grade, push-pull output comparator with integrated 1.242V voltage reference, 3.1μA maximum quiescent current (B-version), 6mV typical built-in hysteresis, and operation from 1.65V to 5.5V supply. It serves as a precision voltage detection element in battery management systems and cluster instrumentation.
For engineers reviewing the TLV3012AQDCKRQ1 datasheet, TLV3012AQDCKRQ1 pinout, TLV3012AQDCKRQ1 application, or TLV3012AQDCKRQ1 equivalent, this page delivers verified electrical specs, SC-70 package details, fail-safe input behavior, power-on-reset timing, and direct alternatives for AEC-Q100 Grade 1 designs.
Technical Context
The TLV3012AQDCKRQ1 implements a rail-to-rail input comparator core with push-pull output stage capable of sourcing and sinking up to 0.5mA, eliminating external pull-up resistors. Its integrated 1.242V series reference provides ±1.5% initial accuracy and 100ppm/°C max drift across –40°C to +125°C.
This "B" variant includes fail-safe inputs tolerant to 0–5.5V independent of V+ supply state and a 1.9ms power-on-reset circuit that forces output low during supply ramp-up. Input common-mode range extends 200mV beyond rails, supporting single-supply operation down to 1.65V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct integration into 1.8V, 3.3V, and 5V automotive subsystems without level-shifting. |
| Quiescent Current | 3.1μA max at TA = –40°C to +125°C - supports multi-year battery life in always-on vehicle monitoring nodes. |
| Reference Voltage | 1.242V ±1.5% - provides stable threshold for precise overvoltage/undervoltage detection without external reference IC. |
| Input Hysteresis | 6mV typical - suppresses chatter on noisy sensor signals without requiring external feedback resistors. |
| Propagation Delay | 2–4μs (B-version, 200mV overdrive) - ensures rapid fault response in safety-critical lane departure warning triggers. |
| Input Common-Mode Range | (V–) – 0.2V to (V+) + 0.2V - allows direct sensing of signals below ground or above supply in automotive signal chains. |
| ESD Rating | HBM ±2000V, CDM ±1000V - meets AEC-Q100-002/-011 requirements for robustness in manufacturing and field environments. |
Pinout & Package
TLV3012AQDCKRQ1 is housed in a 6-pin SC-70 (DCK) package measuring 2.0mm × 2.1mm, optimized for space-constrained automotive PCBs. Pin functions are validated per TI SBOS551D Rev. January 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Comparator output | Push-pull driver capable of sourcing/sinking 0.5mA; no external pull-up required; output low during POR. |
| 2 - V– | Negative supply | Ground or lowest system potential; reference for all voltage measurements and output swing. |
| 3 - IN+ | Non-inverting input | High-impedance node (10¹³Ω) accepting signals up to 5.5V regardless of V+ state (fail-safe). |
| 4 - IN– | Inverting input | High-impedance node (10¹³Ω); differential pair input with ±0.3mV offset at 25°C. |
| 5 - REF | Reference output | Stable 1.242V source; drives ≤10nF load; supplies external circuits or divider networks. |
| 6 - V+ | Positive supply | Primary power rail (1.65–5.5V); POR circuit monitors this pin to assert reset during ramp-up/down. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-Safe Inputs | IN+ and IN– tolerate 0–5.5V even when V+ = 0V, eliminating power sequencing constraints in multi-rail ECUs. |
| Power-On Reset (POR) | 1.9ms output hold-low period ensures deterministic startup and reference stabilization before decision-making begins. |
| Integrated Reference | 1.242V ±1.5% output with 100ppm/°C drift replaces discrete reference ICs, reducing BOM count and layout area. |
| Ultra-Low IQ | 3.1μA max over full temperature range enables use in always-on wake-up comparators for intrusion detection. |
| Rail-to-Rail Input | Accepts signals 200mV beyond supply rails - supports direct battery voltage monitoring from 0V to >5V in 12V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012BQDBVRQ1 | SOT-23-6 (DBV) package; identical electrical specs and AEC-Q100 Grade 1 qualification. | Requires larger PCB footprint (2.9mm × 2.8mm vs. 2.0mm × 2.1mm); same thermal resistance (RθJA = 162.5°C/W). | Select when board layout accommodates SOT-23 or requires compatibility with existing DBV footprints. |
| LM7322QMA/NOPB | Higher-speed dual op-amp (22V/μs slew rate); no integrated reference; 1.25mA IQ; SOIC-8 package. | Not a drop-in replacement; requires external reference and hysteresis network; suited for active filtering not threshold detection. | Choose only if design requires amplification + comparison in one device and can absorb higher power and board area. |
Compared with TLV3012AQDCKRQ1, TLV3012BQDBVRQ1 offers identical functionality in a larger package for easier assembly, while LM7322QMA/NOPB trades ultra-low power and integrated reference for speed and gain-making it unsuitable for direct replacement in battery-sensitive automotive detection roles.

FAQ
What is the operating temperature range for TLV3012AQDCKRQ1?
TLV3012AQDCKRQ1 is qualified for ambient operating temperatures from –40°C to +125°C per AEC-Q100 Grade 1 requirements. All electrical specifications-including quiescent current, reference voltage accuracy, and propagation delay-are guaranteed across this full range, making TLV3012AQDCKRQ1 suitable for under-hood and dashboard-mounted automotive applications.
Does TLV3012AQDCKRQ1 include an integrated voltage reference?
Yes, TLV3012AQDCKRQ1 integrates a precision 1.242V series voltage reference accessible on pin 5 (REF). It delivers ±1.5% initial accuracy, 100ppm/°C max drift over –40°C to +125°C, and supports up to 0.5mA sourcing/sinking. This eliminates the need for external reference ICs in voltage-monitoring designs using TLV3012AQDCKRQ1.
What is the purpose of the Power-On Reset (POR) function in TLV3012AQDCKRQ1?
The POR circuit in TLV3012AQDCKRQ1 asserts a 1.9ms output-low state during V+ supply ramp-up or ramp-down. This ensures deterministic startup behavior and allows the internal 1.242V reference to stabilize before the comparator begins evaluating inputs. During POR, TLV3012AQDCKRQ1's push-pull output is actively driven low, preventing undefined states in downstream logic.
How does the fail-safe input feature work in TLV3012AQDCKRQ1?
TLV3012AQDCKRQ1's IN+ and IN– pins remain high-impedance and functional across 0–5.5V even when V+ is unpowered or ramping. This avoids false outputs during power sequencing mismatches. As long as one input stays within its valid range and V+ is stable, TLV3012AQDCKRQ1 delivers correct output polarity-critical for reliable operation in multi-supply automotive ECUs.
Can TLV3012AQDCKRQ1 operate from a 1.65V supply?
Yes, TLV3012AQDCKRQ1 supports a minimum supply voltage of 1.65V-lower than the 1.8V minimum of non-B variants. This enables direct interface with energy-harvesting circuits and ultra-low-voltage battery monitoring in automotive applications where supply rails dip near cutoff. Full functionality-including reference output and comparator operation-is maintained across 1.65V to 5.5V.
