Product details
Overview
TLV3201AQDCKRQ1 from Texas Instruments is a single-channel automotive-grade comparator with 40 ns propagation delay, 40 µA quiescent current, and rail-to-rail input extending 200 mV beyond supply rails. It features push-pull output, 1 mV input offset voltage, and operates from 2.7 V to 5.5 V - enabling fast, low-power threshold detection in engine control units and battery management systems.
For engineers reviewing the TLV3201AQDCKRQ1 datasheet, TLV3201AQDCKRQ1 pinout, TLV3201AQDCKRQ1 application, or TLV3201AQDCKRQ1 equivalent, key selection criteria include propagation delay vs. overdrive, input common-mode range beyond rails, push-pull drive capability, AEC-Q100 Grade 1 qualification (–40°C to +125°C), and SC70-5 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV3201AQDCKRQ1 implements a high-speed bipolar input stage with internal 1.2 mV hysteresis for noise immunity and no phase inversion when inputs exceed supply rails. Its push-pull output delivers ±4 mA sourcing/sinking at 5 V and supports direct interfacing with CMOS logic without pull-up resistors.
It is specified across –40°C to +125°C ambient temperature with HBM ESD rating of ±3 kV and CDM rating of ±750 V. Input bias current remains below 50 pA at 25°C, and common-mode rejection ratio exceeds 60 dB over full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 40 ns typical (low-to-high/high-to-low) at 20 mV overdrive, CL = 15 pF - enables sub-25 MHz pulse-width monitoring and zero-cross detection. |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct connection to 3.3 V or 5 V automotive domains without level-shifting. |
| Input Offset Voltage | 1 mV max at 25°C, 6 mV max over –40°C to +125°C - ensures accurate trip-point stability in precision threshold applications. |
| Quiescent Current | 40 µA typical at 25°C, 65 µA max over temperature - enables always-on sensing in battery-backed modules. |
| Input Common-Mode Range | Extends 200 mV beyond both rails (e.g., –0.2 V to 5.7 V at 5 V supply) - tolerates ground offsets and transient coupling in noisy vehicle environments. |
| Output Type | Push-pull - eliminates need for external pull-up, reduces BOM count, and drives CMOS loads directly with rail-aligned logic levels. |
| ESD Rating | HBM ±3000 V, CDM ±750 V - meets AEC-Q100-002/-011 requirements for under-hood and cabin electronics robustness. |
Pinout & Package
TLV3201AQDCKRQ1 is housed in a 5-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for high-density automotive PCBs and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Comparator output | Push-pull digital output capable of sourcing/sinking ≥4 mA - interfaces directly with MCU GPIO or logic gates without external components. |
| IN– (Pin 4) | Inverting input | Differential input node with rail-to-rail common-mode range and <50 pA bias current - minimizes error in high-impedance sensor interfaces. |
| IN+ (Pin 3) | Non-inverting input | Differential input node matching IN– characteristics - supports both inverting and non-inverting configurations with external hysteresis networks. |
| GND (Pin 2) | Negative supply reference | Ground return path for internal circuitry and output stage - requires low-impedance connection to system ground plane for noise immunity. |
| VCC (Pin 5) | Positive supply | Single-supply input (2.7–5.5 V) powering all internal stages - decoupling capacitor (0.1 µF) recommended adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - suitable for engine bay, transmission, and powertrain control modules. |
| 40 ns propagation delay | Enables real-time response to fast transients such as PWM edge detection or fault-triggered shutdown signals. |
| Rail-to-rail input with 200 mV beyond-rail tolerance | Eliminates need for external level-shifting in systems with ground potential mismatches (e.g., sensor-to-ECU cabling). |
| Internal 1.2 mV hysteresis | Reduces false triggering from EMI or signal noise without requiring external feedback components. |
| Push-pull output architecture | Provides defined logic-high and logic-low states - avoids bus contention and simplifies interface with 3.3 V/5 V digital subsystems. |
Applications
| Engine Control Unit (ECU) Timing Monitor | Battery Management System (BMS) Cell Overvoltage Detection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7239QDRQ1 | 75 ns propagation delay, 65 µA IQ, same push-pull output and AEC-Q100 Grade 1 rating. | Lower speed limits use in >10 MHz PWM monitoring; higher IQ increases battery drain in always-on BMS nodes. | Select when cost sensitivity outweighs speed requirement and existing layout accommodates VSSOP-8 footprint. |
| TLV3501CDCKR | 4.5 ns propagation delay, 5.5 mA IQ, open-drain output, non-automotive grade. | Ultra-fast response suits LIDAR pulse discrimination but lacks AEC-Q100 qualification and requires pull-up resistor. | Choose only for non-automotive high-speed test equipment where qualification and power efficiency are secondary. |
Compared with LMV7239QDRQ1 and TLV3501CDCKR, TLV3201AQDCKRQ1 uniquely balances 40 ns speed, 40 µA ultra-low power, AEC-Q100 compliance, and SC70-5 footprint - making it optimal for space- and energy-constrained automotive real-time monitoring nodes where drop-in replacement is not required but functional superiority in speed/power trade-off is critical.

FAQ
What is the maximum operating temperature range for TLV3201AQDCKRQ1?
The TLV3201AQDCKRQ1 is qualified per AEC-Q100 Grade 1 and operates reliably from –40°C to +125°C ambient temperature. This range covers under-hood environments and powertrain control modules. The device's thermal metrics - including RθJA of 281.9°C/W in SC70 - support sustained operation within this envelope when properly mounted on a thermally adequate PCB.
Does TLV3201AQDCKRQ1 require external hysteresis for noise immunity?
No - TLV3201AQDCKRQ1 includes 1.2 mV of internal hysteresis, which improves noise immunity without external components. This built-in hysteresis is sufficient for most automotive applications with moderate EMI, such as crankshaft position monitoring or cell voltage thresholding. External hysteresis networks remain optional for cases demanding larger trip windows.
Can TLV3201AQDCKRQ1 operate from a 3.3 V supply?
Yes - TLV3201AQDCKRQ1 supports supply voltages from 2.7 V to 5.5 V, fully covering 3.3 V nominal systems. At 3.3 V, propagation delay remains ≤55 ns over temperature, output swing stays within 230 mV of rails (sinking 4 mA), and quiescent current is ≤60 µA - ensuring compatibility with modern low-voltage automotive microcontrollers and sensors.
Is TLV3201AQDCKRQ1 pin-compatible with any dual-channel alternatives?
No - TLV3201AQDCKRQ1 is a single-channel SC70-5 device. Its dual-channel counterpart TLV3202AQDGKRQ1 uses an 8-pin VSSOP package with different pinout and is not pin-compatible. Direct replacement would require PCB redesign. For space-constrained dual-channel needs, consider discrete placement of two TLV3201AQDCKRQ1 units with shared supply decoupling.
What packaging and marking information is associated with TLV3201AQDCKRQ1?
TLV3201AQDCKRQ1 is supplied in tape-and-reel format in a 5-pin SC70 (DCK) package, body size 2.00 mm × 1.25 mm. Top-side marking includes "A1" followed by a date code and factory traceability symbols. The "Q1" suffix confirms AEC-Q100 qualification, and "DCK" denotes the SC70 package variant - distinct from VSSOP or SOIC versions in the same family.
