Product details
Overview
TLV9030QDCKRQ1 from Texas Instruments is a single-channel, push-pull output precision comparator in SC-70 (DCK) package, featuring 300 µV max input offset voltage, 100 ns propagation delay, and rail-to-rail fault-tolerant inputs operating from 1.65 V to 5.5 V supply. It delivers low 16 µA quiescent current per channel and supports industrial temperature range (–40°C to +125°C), enabling precise voltage monitoring in motor drives and automotive infotainment systems.
For engineers reviewing the TLV9030QDCKRQ1 datasheet, TLV9030QDCKRQ1 pinout, TLV9030QDCKRQ1 application, or TLV9030QDCKRQ1 equivalent, this page provides verified technical context, pin-level design meaning, real-world use cases in harsh environments, and validated alternative options for precision comparator selection.
Technical Context
The TLV9030QDCKRQ1 implements a high-speed, low-power comparator core with push-pull output stage capable of sourcing/sinking ≥4 mA, enabling direct LED drive or MOSFET gate control without external pull-up. Its fault-tolerant inputs withstand up to 6 V independent of supply, preventing phase inversion during overvoltage transients.
Designed for precision voltage threshold detection, it combines 0.5 µV/°C input offset drift, 70 dB CMRR at 5 V, and 95 dB PSRR - ensuring stable decision-making in noisy factory automation and automotive subsystems where supply ripple and EMI are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Offset Voltage | ±0.3 mV max - enables accurate detection of sub-millivolt voltage differences in battery monitoring or sensor thresholds. |
| Propagation Delay | 100 ns (high-to-low), 115 ns (low-to-high) - ensures timely response in fast-cycling motor control feedback loops. |
| Quiescent Current | 16 µA per channel - allows always-on monitoring in power-constrained automotive body electronics. |
| Input Bias Current | 5 pA - minimizes loading error on high-impedance sources like thermistors or photodiodes. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100 Grade 1. |
| Fault-Tolerant Inputs | Withstand –0.3 V to 6 V relative to V– - eliminates need for external clamping diodes in noisy industrial I/O modules. |
Pinout & Package
TLV9030QDCKRQ1 uses the 5-pin SC-70 (DCK) package (1.25 mm × 2.00 mm), optimized for space-constrained PCB layouts in automotive and portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Push-pull output | Drives loads directly: sinks/source ≥4 mA; no external pull-up required; compatible with 1.8 V/3.3 V logic inputs. |
| 2: V– | Negative supply | Reference node for all inputs and output; thermal pad (in DCK) must be connected to this pin for thermal performance. |
| 3: IN– | Inverting input | Accepts signals up to 6 V above V–; internal ESD clamps prevent damage during transient events. |
| 4: IN+ | Non-inverting input | Same fault tolerance as IN–; differential input voltage range supports precise threshold comparison. |
| 5: V+ | Positive supply | Supplies internal bias circuitry; decoupling capacitor (0.1 µF) recommended within 2 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9030QDBVRQ1 | SOT-23-5 (DBV) package; identical electrical specs and AEC-Q100 qualification. | Larger footprint (1.60 mm × 2.90 mm) vs. DCK (1.25 mm × 2.00 mm); higher RθJA (223.7°C/W vs. 238.5°C/W). | Select when board layout requires SOT-23 compatibility or manual assembly preference. |
| LMV7219M5X/NOPB | Higher 2.7 V min supply; 45 ns propagation delay; no AEC-Q100 qualification; 65 µA IQ. | Not automotive-qualified; better speed but higher power - suited for cost-sensitive industrial controls, not safety-critical automotive. | Choose only for non-automotive designs where speed outweighs power and qualification requirements. |
Compared with TLV9030QDCKRQ1, TLV9030QDBVRQ1 offers identical performance in a larger, more hand-solderable package, while LMV7219M5X/NOPB trades automotive qualification and ultra-low power for faster response in commercial-grade systems.

FAQ
What is the maximum input voltage tolerance for TLV9030QDCKRQ1?
The TLV9030QDCKRQ1 features fault-tolerant inputs rated from –0.3 V to 6 V relative to V–, regardless of supply voltage. This allows safe operation during transients such as load dump or ESD events without external protection components - a key advantage in automotive and industrial applications where input overvoltage is common.
Does TLV9030QDCKRQ1 support rail-to-rail input common-mode range?
Yes, TLV9030QDCKRQ1 supports a common-mode input voltage range from (V–) – 0.2 V to (V+) + 0.2 V across its full operating temperature range. This rail-to-rail capability ensures accurate comparison even when input signals approach or slightly exceed the supply rails - critical for battery voltage monitoring and sensor signal conditioning.
What is the output drive capability of TLV9030QDCKRQ1?
TLV9030QDCKRQ1 has a push-pull output capable of sourcing and sinking ≥4 mA at 25°C (with 175 mV saturation voltage at –40°C to +125°C). This allows direct interface with logic inputs, LEDs, small solenoids, or MOSFET gates - eliminating external driver stages and reducing system component count.
Is TLV9030QDCKRQ1 qualified for automotive applications?
Yes, TLV9030QDCKRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C), with full characterization for automotive use including ESD (2 kV HBM), latch-up immunity, and long-term reliability testing. Its DCK package and specifications meet OEM requirements for body electronics, infotainment, and powertrain subsystems.
How does TLV9030QDCKRQ1 differ from TLV9020QDCKRQ1?
TLV9030QDCKRQ1 features a push-pull output, while TLV9020QDCKRQ1 uses an open-drain output. This means TLV9030QDCKRQ1 can actively drive high and low states without external pull-up resistors - simplifying designs requiring bidirectional logic-level signaling or direct LED/MOSFET control, unlike TLV9020QDCKRQ1 which requires external pull-up for high-state assertion.
