Product details
Overview
TLV3601QDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive high-speed comparator with 2.5 ns propagation delay, 325 MHz toggle frequency, and 1.25 ns minimum pulse width detection capability. It features rail-to-rail inputs extending 200 mV beyond both supply rails, ±5 mV input offset voltage, and push-pull output - enabling precise zero-crossing detection and fast signal conditioning in LIDAR time-of-flight systems.
For engineers reviewing the TLV3601QDCKRQ1 datasheet, TLV3601QDCKRQ1 pinout, TLV3601QDCKRQ1 application, or TLV3601QDCKRQ1 equivalent, this device is selected for narrow-pulse timing-critical circuits where propagation delay consistency, overdrive dispersion (600 ps), and wide 2.4 V–5.5 V supply operation directly impact system-level timing accuracy and noise immunity.
Technical Context
The TLV3601QDCKRQ1 implements a single-channel, rail-to-rail input comparator core with a push-pull output stage optimized for minimal propagation delay variation across temperature and overdrive conditions. Its internal Power-on-Reset (POR) circuit ensures known low-state startup at VCC < 2.1 V, eliminating output glitches during power ramp-up.
Unlike TLV3603-Q1, it lacks LE/HYST pin functionality - operating exclusively in active comparison mode with fixed hysteresis (1.5–5 mV). Input common-mode range spans VEE – 0.2 V to VCC + 0.2 V, supporting direct sensing of signals crossing ground or near supply rails without level-shifting.
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 distance measurement |
| Toggle frequency | 325 MHz maximum; supports high-speed data recovery and clock regeneration in serial interfaces |
| Min. input pulse width | 1.25 ns; allows detection of ultra-short transients in motor phase current sensing or laser pulse edges |
| Input offset voltage | ±5 mV max (–40°C to +125°C); ensures consistent threshold accuracy across automotive temperature range |
| Supply voltage range | 2.4 V to 5.5 V; compatible with 3.3 V and 5 V logic domains and battery-supplied automotive subsystems |
| Overdrive dispersion | 600 ps max; guarantees stable timing margins when input overdrive varies across system operating conditions |
| Input common-mode range | VEE – 0.2 V to VCC + 0.2 V; permits direct connection to unbuffered sensor outputs crossing rail boundaries |
Pinout & Package
TLV3601QDCKRQ1 is packaged in a 5-pin SC70 (DCK) package measuring 1.25 mm × 2.00 mm, optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Non-inverting input | Differential input node accepting signals up to 200 mV beyond VCC or below VEE; used for reference or signal path |
| IN− | Inverting input | Differential input node with identical rail-to-rail range; forms comparison pair with IN+ |
| OUT | Push-pull output | CMOS-compatible single-ended output driving high/low directly to VCC/VEE without external pull-up |
| VEE | Negative supply / ground | Reference return for input stage and output driver; supports true ground-referenced operation |
| VCC | Positive supply | Primary power rail (2.4–5.5 V); powers internal biasing, amplification, and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Operates with inputs 200 mV beyond VEE and VCC - enables direct interface to sensors and transducers without level shifters |
| Known startup condition | Power-on-reset holds OUT low until VCC ≥ 2.1 V - eliminates undefined output states during cold cranking or wake-up |
| Low overdrive dispersion | 600 ps max variation in propagation delay across 10–125 mV overdrive - preserves timing integrity in variable-signal-amplitude systems |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C ambient), HBM ±2 kV, CDM ±1 kV - validated for under-hood and ADAS module deployment |

FAQ
What is the maximum operating temperature range for TLV3601QDCKRQ1?
The TLV3601QDCKRQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. This rating is verified across all electrical parameters in the datasheet, including propagation delay, input offset voltage, and supply current, ensuring reliable operation in under-hood automotive environments.
Does TLV3601QDCKRQ1 support rail-to-rail input operation?
Yes, TLV3601QDCKRQ1 supports rail-to-rail input operation with a common-mode voltage range extending 200 mV beyond both VEE and VCC rails (VEE – 0.2 V to VCC + 0.2 V). This enables direct interfacing with sensors and transducers whose outputs swing below ground or above supply without external level-shifting circuitry.
What is the purpose of the Power-on-Reset (POR) circuit in TLV3601QDCKRQ1?
The POR circuit in TLV3601QDCKRQ1 holds the output low (at VEE) whenever VCC is below 2.1 V. This ensures a known, safe startup state during power-up or brownout conditions - preventing spurious switching in downstream logic and eliminating the need for external reset supervision in automotive modules.
Can TLV3601QDCKRQ1 be used with a single 3.3 V supply?
Yes, TLV3601QDCKRQ1 operates fully across 2.4 V to 5.5 V, including standard 3.3 V supplies. At 3.3 V, it delivers 2.5 ns typical propagation delay, 325 MHz toggle frequency, and maintains ±5 mV input offset voltage over –40°C to +125°C - making it ideal for 3.3 V automotive microcontroller I/O interfacing.
How does TLV3601QDCKRQ1 differ from TLV3603-Q1?
TLV3601QDCKRQ1 is a single-channel comparator with fixed hysteresis and no latch function, while TLV3603-Q1 adds a 6th pin (LE/HYST) for adjustable hysteresis control and latching. TLV3601QDCKRQ1 uses a 5-pin SC70 package; TLV3603-Q1 requires a 6-pin SC70. Both share identical speed, supply range, and automotive qualification.
