Product details
Overview
TLV3602QDGKRQ1 from Texas Instruments is a dual-channel, automotive-grade high-speed comparator with 2.5 ns propagation delay, 325 MHz toggle frequency, and rail-to-rail inputs extending 200 mV beyond both supply rails. It operates from 2.4 V to 5.5 V and delivers ±5 mV input offset voltage and 1.25 ns minimum pulse width detection-enabling precise timing in LIDAR time-of-flight and BMS overvoltage monitoring circuits.
For engineers reviewing the TLV3602QDGKRQ1 datasheet, TLV3602QDGKRQ1 pinout, TLV3602QDGKRQ1 application, or TLV3602QDGKRQ1 equivalent, key selection criteria include dual-channel propagation skew (24 ps), push-pull output drive capability, AEC-Q100 Grade 1 qualification (–40°C to +125°C), and VSSOP-8 package compatibility with space-constrained automotive control modules.
Technical Context
The TLV3602QDGKRQ1 implements two independent high-speed comparator cores sharing a common V+ and V− supply pair, each with fully differential rail-to-rail input stages and push-pull CMOS outputs. Its internal Power-on-Reset circuit ensures known low-state startup until VCC ≥ 2.1 V, eliminating undefined output behavior during power ramp-up.
Unlike TLV3603-Q1, it lacks latch/hysteresis control pins and operates exclusively in active-compare mode. Input common-mode range spans VEE – 0.2 V to VCC + 0.2 V, and output drive strength supports 1 mA sourcing/sinking with <80 mV VOL/VOH at full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 2.5 ns typical (50 mV overdrive); enables sub-nanosecond timing resolution in time-of-flight systems |
| Toggle frequency | 325 MHz maximum; supports high-speed data recovery in serial links and clock regeneration |
| Input offset voltage | ±5 mV max over –40°C to +125°C; ensures accurate threshold detection without calibration |
| Supply voltage range | 2.4 V to 5.5 V; compatible with 3.3 V and 5 V automotive subsystems and battery-powered sensors |
| Input common-mode range | VEE – 0.2 V to VCC + 0.2 V; allows zero-crossing detection and wide dynamic signal capture |
| Minimum pulse width | 1.25 ns; detects narrow transients in motor phase current sensing and fault event capture |
| Channel-to-channel skew | 24 ps max; maintains tight timing alignment between dual outputs for synchronous sampling |
Pinout & Package
TLV3602QDGKRQ1 is packaged in an 8-pin VSSOP (DGK) with 3.00 mm × 3.00 mm body size and exposed thermal pad connected to V−. The package supports automated optical inspection and offers 170.5°C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+ | Non-inverting input, channel 1 | Accepts analog signals up to 200 mV beyond V− or V+; used for reference comparison in BMS cell monitoring |
| IN1− | Inverting input, channel 1 | Differential partner to IN1+; forms first high-speed decision path for overvoltage or edge detection |
| IN2− | Inverting input, channel 2 | Second comparator input; enables simultaneous monitoring of two independent signals (e.g., motor phase A/B) |
| IN2+ | Non-inverting input, channel 2 | Independent threshold input for second channel; supports redundant sensing or dual-slope ADC front-end |
| OUT1 | Output, channel 1 | Push-pull CMOS output driving directly into FPGA I/O or microcontroller interrupt pin without external pull-up |
| OUT2 | Output, channel 2 | Matched-output stage with <24 ps skew to OUT1; critical for synchronized digital capture in safety-critical control loops |
| V− | Negative supply / ground | Reference node for both channels and thermal pad connection point; must be low-impedance for noise immunity |
| V+ | Positive supply | Single shared supply rail for both comparators; simplifies power routing in dual-signal monitoring applications |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with HBM ±2 kV and CDM ±500 V ESD robustness |
| Known startup condition | Power-on-reset holds both outputs low until VCC ≥ 2.1 V, preventing spurious interrupts during power sequencing |
| Rail-to-rail input stage | Supports input voltages 200 mV below V− and above V+, enabling direct interface with unbuffered sensor outputs |
| Push-pull output architecture | Eliminates need for external pull-up resistors, reducing board area and power consumption in high-frequency switching |
| Dual-channel integration | Two matched comparators in one VSSOP-8 package reduce component count and inter-channel timing mismatch vs. discrete solutions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3602DRQ1 | Same dual-channel architecture and specs, but in SOIC-8 package (4.9 mm × 3.9 mm); higher RθJA (195°C/W) than VSSOP-8 | Preferred for prototyping or manual assembly where board space is less constrained | Select when thermal margin allows larger footprint and hand-soldering is required |
| LMH7322MQX/NOPB | 2.8 ns propagation delay, 300 MHz toggle, but single-supply only (2.7–12 V); no AEC-Q100 qualification | Suitable for industrial test equipment but not automotive safety-critical systems | Choose only for non-automotive designs requiring wider supply range and higher voltage tolerance |
Compared with TLV3602QDGKRQ1, TLV3602DRQ1 trades compact VSSOP-8 size and better thermal performance for easier handling, while LMH7322MQX/NOPB offers broader voltage support but lacks automotive qualification and dual-channel skew control-making TLV3602QDGKRQ1 optimal for space- and timing-critical automotive subsystems.

FAQ
What is the maximum operating temperature range for TLV3602QDGKRQ1?
The TLV3602QDGKRQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. This rating is validated across all electrical parameters including propagation delay, input offset voltage, and output drive strength, ensuring reliable operation in under-hood automotive environments.
Does TLV3602QDGKRQ1 support rail-to-rail input operation?
Yes, TLV3602QDGKRQ1 supports rail-to-rail input operation with a common-mode range extending 200 mV beyond both V− and V+ rails (i.e., VEE – 0.2 V to VCC + 0.2 V). This enables direct interfacing with sensors and amplifiers that swing near or slightly outside supply rails without external level-shifting circuitry.
What is the function of the thermal pad on the TLV3602QDGKRQ1 VSSOP-8 package?
The thermal pad on the TLV3602QDGKRQ1 VSSOP-8 (DGK) package is internally connected to the V− pin and must be soldered to a PCB copper pour tied to the system ground plane. It reduces junction-to-board thermal resistance to 92.4°C/W, improving power dissipation and long-term reliability in continuous high-speed operation.
Can TLV3602QDGKRQ1 replace TLV3601QDGKRQ1 in a design?
No-TLV3602QDGKRQ1 is a dual-channel device in VSSOP-8, while TLV3601QDGKRQ1 is single-channel in SC70-5 or SOT23-5. Pin count, pinout, and channel count differ fundamentally. A direct replacement requires redesigning the schematic and layout to accommodate two independent comparator channels and the 8-pin footprint.
What is the purpose of the Power-on-Reset (POR) circuit in TLV3602QDGKRQ1?
The POR circuit in TLV3602QDGKRQ1 holds both outputs low (at V−) until VCC reaches ≥2.1 V, ensuring a deterministic startup state. This prevents false triggering of downstream logic during power-up ramp, which is essential in automotive systems where uncontrolled interrupts could compromise functional safety integrity.
