Applications
The TLV3601-Q1 is used in automotive powertrain and ADAS systems for rapid analog threshold detection, such as battery cell voltage monitoring and motor current overcurrent sensing, thanks to its 4.5 ns propagation delay and AEC-Q100 Grade 1 qualification. Industrial designs leverage it in pulse-width discriminators, zero-crossing detectors, and high-speed clock comparators operating at 2.7 V to 5.5 V. Its tiny 5-pin SC70 package also makes it ideal for compact IoT edge nodes and portable instruments where board space is at a premium.

Frequently Asked Questions
How fast is the TLV3601-Q1 comparator response and in which designs does this speed matter?
The TLV3601-Q1 achieves a propagation delay of 4.5 ns, making it one of the fastest single-channel comparators in Texas Instruments' portfolio. This speed is critical in motor control overcurrent protection, high-frequency pulse detection, and LIDAR proximity sensing where sub-10 ns response is required to prevent damage or missed events.
What supply voltage range does the TLV3601-Q1 support and which logic families can it interface with?
The TLV3601-Q1 operates from a supply voltage of 2.7 V to 5.5 V, enabling direct interfacing with 3.3 V CMOS logic and 5 V TTL logic families. Its open-drain output stage allows the pull-up resistor to set the output high level independently, making it compatible with systems using 1.8 V, 3.3 V, or 5 V logic thresholds.
What automotive qualification does the TLV3601-Q1 carry and over what temperature range does it operate?
The TLV3601-Q1 is AEC-Q100 Grade 1 qualified for automotive-grade reliability, operating across a junction temperature range of -40°C to 125°C. This qualification ensures it meets the stringent reliability and testing requirements of automotive powertrain, chassis, and body electronics applications.
For a compact automotive sensor design, how much board space does the TLV3601-Q1 SC70 package require?
The TLV3601-Q1 is housed in a 5-pin SC70 package with a footprint of approximately 2 mm x 2.1 mm and a height of 1.0 mm, consuming less than 4.2 mm² of PCB area. This makes it one of the smallest single-comparator packages available, ideal for automotive sensor modules and wearable electronics where board space is at a premium.
When is TLV3601-Q1 preferred over a general-purpose comparator like LM393 for a motor protection circuit?
The TLV3601-Q1 outperforms the LM393 in motor overcurrent protection circuits because its 4.5 ns propagation delay is roughly 1,000 times faster than the LM393's typical 1.3 µs delay, enabling near-instantaneous fault detection. Combined with AEC-Q100 Grade 1 automotive qualification and a 5.5 V maximum supply, it suits high-reliability automotive motor controllers where LM393 would respond too slowly to prevent damage.
