Key Features
- Factory-set trip point at +125°C with integrated hysteresis for reliable switching without external components
- Wide supply voltage range of 2.7 V to 5.5 V suits both 3.3 V and 5 V system rails
- Ultra-compact SOT-23-5 package enables space-saving board layouts in thermally sensitive designs
Applications
TC6501P125VCTTR is used in over-temperature protection circuits for power supplies, motor drivers, and battery management systems where a fixed +125°C trip point is required. Its open-drain output directly drives a microcontroller interrupt or a load-switch gate without additional level-shifting circuitry. The device is also suited for thermal monitoring in industrial equipment operating in harsh environments up to +125°C.

Frequently Asked Questions
At what temperature does the TC6501P125VCTTR switch its output, and what hysteresis value prevents output chatter?
The TC6501P125VCTTR has a factory-set trip point of +125°C. It incorporates built-in hysteresis of approximately 10°C so the output does not chatter when the temperature hovers near the threshold, ensuring stable switching behavior in noisy thermal environments.
Which supply voltage range is compatible with TC6501P125VCTTR, and can it work directly on a 3.3 V rail?
TC6501P125VCTTR operates from 2.7 V to 5.5 V, so a 3.3 V rail is fully supported without any regulation. This wide range also accommodates 5 V legacy systems, making the device versatile across mixed-voltage designs.
How does the SOT-23-5 package of TC6501P125VCTTR benefit compact PCB layouts in thermal-management applications?
The SOT-23-5 package measures approximately 2.9 mm × 1.6 mm, occupying minimal PCB footprint. This allows the TC6501P125VCTTR to be placed close to the heat source on a dense board, improving thermal response time compared to larger TO-92 or SOIC-8 packages.
When should a designer choose TC6501P125VCTTR over a programmable temperature sensor such as a TC74?
TC6501P125VCTTR is ideal when a fixed +125°C threshold is acceptable and no I2C bus is available or desired, since it requires 0 firmware lines to operate. TC74 offers programmable alerts over I2C but adds software complexity; TC6501P125VCTTR saves both code space and 2-wire bus resources in simple over-temperature cut-off circuits.
