Product details
Overview
TLV3202AQDGKRQ1 from Texas Instruments is a dual-channel, automotive-qualified comparator with 40 ns propagation delay, 40 µA quiescent current per channel, and rail-to-rail inputs extending 200 mV beyond supply rails. It features push-pull outputs, operates from 2.7 V to 5.5 V, and is qualified to AEC-Q100 Grade 1 (–40°C to +125°C), making it suitable for engine control units and battery management systems.
For engineers reviewing the TLV3202AQDGKRQ1 datasheet, TLV3202AQDGKRQ1 pinout, TLV3202AQDGKRQ1 application, or TLV3202AQDGKRQ1 equivalent, key selection criteria include propagation delay vs. overdrive, input offset voltage drift (≤10 µV/°C), output drive capability (≥40 mA sink/source at 5 V), and ESD robustness (HBM ±4 kV, CDM ±750 V).
Technical Context
The TLV3202AQDGKRQ1 integrates two independent high-speed comparators in a single 8-pin VSSOP package, each with internal 1.2 mV hysteresis for noise immunity and no phase inversion under overvoltage conditions. Its input stage uses back-to-back ESD diodes with 1-kΩ series resistors to clamp differential inputs exceeding supply rails.
It supports single-supply operation from 2.7 V to 5.5 V (±1.35 V to ±2.75 V dual) and maintains specified performance across –40°C to +125°C. Propagation delay remains stable across input overdrive (20–100 mV), capacitive load (up to 15 pF), and common-mode voltage (–0.2 V to VCC + 0.2 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 40 ns typical (low-to-high/high-to-low), enabling precise timing in PWM monitoring and zero-cross detection circuits |
| Quiescent current | 40 µA per channel at 25°C, supporting ultra-low-power operation in battery-backed automotive modules |
| Input offset voltage | 1 mV max at 25°C, ensuring accurate threshold detection without external trimming |
| Supply voltage range | 2.7 V to 5.5 V, compatible with standard 3.3 V and 5 V automotive power domains |
| Input common-mode range | Extends 200 mV beyond either rail (–0.2 V to VCC + 0.2 V), allowing direct sensing of signals near ground or supply |
| Output type | Push-pull, delivering full-rail swing (e.g., 175 mV low / 120 mV high at 4 mA load, 5 V supply) |
| ESD rating | HBM ±4000 V, CDM ±750 V - meets AEC-Q100-002/-011 for harsh automotive environments |
Pinout & Package
TLV3202AQDGKRQ1 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained automotive PCB layouts and thermally efficient mounting on small copper areas.

| 1OUT | Output, comparator 1 | Push-pull output capable of sourcing/sinking ≥40 mA; no external pull-up required |
| GND | Negative supply, ground | Reference return path for both comparators and output stage; must be low-impedance |
| 2IN– | Negative input, comparator 2 | Independent differential input for second comparator; electrically isolated from channel 1 |
| 2IN+ | Positive input, comparator 2 | Independent differential input for second comparator; supports same rail-to-rail common-mode range |
| 2OUT | Output, comparator 2 | Second push-pull output, matched in delay (<5 ns skew) and drive strength to 1OUT |
| VCC | Positive supply | Single supply pin powering both comparators; decoupling capacitor (0.1 µF) required adjacent to pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7239QDGKRQ1 | 75 ns propagation delay, 65 µA IQ, same VSSOP-8 package and AEC-Q100 Grade 1 rating | Lower speed limits use in PWM edge detection; higher IQ increases battery drain in always-on BMS nodes | Choose when cost sensitivity outweighs timing performance, or where existing LMV7239Q layout reuse is prioritized |
| TLV3702QDRQ1 | 120 ns propagation delay, 1.8 µA IQ, rail-to-rail input, open-drain output, SOT-23-8 package | Open-drain output requires external pull-up; lower IQ suits ultra-low-power wake-up circuits but lacks push-pull drive | Prefer for standby-mode threshold detection where output loading is light and power budget is <5 µA per channel |
Compared with LMV7239QDGKRQ1 and TLV3702QDRQ1, TLV3202AQDGKRQ1 delivers the fastest response (40 ns) and strongest output drive (push-pull, >40 mA) in an automotive-qualified dual comparator, making it optimal for safety-critical real-time protection and high-frequency signal conditioning where latency and robustness are non-negotiable.

FAQ
What is the maximum operating temperature range for TLV3202AQDGKRQ1?
The TLV3202AQDGKRQ1 is qualified for AEC-Q100 Grade 1 operation, with a guaranteed ambient operating temperature range of –40°C to +125°C. Electrical specifications including propagation delay, offset voltage, and output drive are fully characterized across this range, and junction temperature must not exceed 150°C under normal operation.
Does TLV3202AQDGKRQ1 support rail-to-rail input operation?
Yes, TLV3202AQDGKRQ1 supports true rail-to-rail input operation with a common-mode voltage range extending 200 mV beyond both supply rails (–0.2 V to VCC + 0.2 V). This allows direct interfacing with sensors or signals referenced to ground or VCC, eliminating level-shifting circuitry in most automotive applications.
What is the output configuration of TLV3202AQDGKRQ1?
TLV3202AQDGKRQ1 features push-pull (totem-pole) outputs on both channels. Each output can source and sink up to 48 mA (sink) or 60 mA (source) at 5 V supply, delivering full-rail logic levels without external pull-up resistors - simplifying interface design with MCUs and FPGA inputs.
How does TLV3202AQDGKRQ1 handle input overvoltage conditions?
TLV3202AQDGKRQ1 incorporates internal ESD diodes and 1-kΩ series input resistors that clamp input voltages exceeding the supply rails by >300 mV. As long as input current is limited to ≤10 mA (e.g., via external series resistor), the device avoids damage and maintains correct functionality without phase inversion - a key reliability feature for noisy automotive environments.
Is TLV3202AQDGKRQ1 pin-compatible with other dual comparators in VSSOP-8?
No, TLV3202AQDGKRQ1 has a unique pinout optimized for dual independent operation: pins 1/2/3 serve comparator 1 (1OUT/1IN–/1IN+), pins 6/5/7 serve comparator 2 (2IN–/2IN+/2OUT), with GND on pin 4 and VCC on pin 8. It is not pin-compatible with LMV7239QDGKRQ1 or TLV3702QDRQ1 - PCB layout must follow TI's DGK package diagram.
