Key Features
- Fixed temperature trip point at plus 5 degrees C with 5 degrees C hysteresis prevents output chatter near threshold
- No external components required: internal bandgap reference and comparator in SOT-23-5
- Open-drain output compatible with 2.7 V to 5.5 V logic levels for easy MCU interfacing
- Tiny SOT-23-5 package occupies minimal board area for space-constrained thermal protection circuits
Applications
The TC6504P005VCTTR is designed for low-cost thermal monitoring applications such as battery-pack over-temperature protection, server fan controllers, and HVAC equipment where a hard 5 degrees C trip with built-in 5 degrees C hysteresis eliminates the need for external RC networks. Its simple 2-wire connection to any open-drain GPIO makes it straightforward to integrate into industrial sensors, white-goods appliances, and portable instruments that need reliable cold-temperature detection without a full ADC channel.

Frequently Asked Questions
At what temperature does the TC6504P005VCTTR assert its output and what hysteresis prevents relay chatter?
The TC6504P005VCTTR triggers at a fixed threshold of plus 5 degrees C and applies 5 degrees C of built-in hysteresis, so the output de-asserts only after the temperature rises to approximately plus 10 degrees C. This hysteresis window prevents rapid on-off toggling when the ambient temperature hovers near the trip point, which is critical for fan controllers and relay-driven circuits.
What supply voltage range does the TC6504P005VCTTR support for 3.3 V and 5 V embedded systems?
The TC6504P005VCTTR operates from a supply voltage of 2.7 V to 5.5 V, making it directly compatible with both 3.3 V and 5 V microcontroller boards. The open-drain output can be pulled up to the local logic supply rail, and the low quiescent current draws typically less than 50 µA, extending battery life in portable thermal-monitoring applications.
How does the TC6504P005VCTTR simplify BOM compared to a discrete temperature-switch design using a thermistor and comparator?
The TC6504P005VCTTR integrates a bandgap temperature sensor, comparator, and fixed-threshold reference into a single SOT-23-5 device, replacing at least 4 discrete components (thermistor, resistor divider, comparator IC, and bypass capacitor) in a traditional design. This reduces PCB area by several square millimeters and eliminates calibration, since the 5 degrees C trip point is factory-trimmed to within a tight tolerance.
Which industries commonly use the TC6504P005VCTTR for cold-temperature detection in their products?
The TC6504P005VCTTR is widely used in refrigeration and cold-chain equipment that must detect temperatures near 0 degrees C to 5 degrees C, as well as in Li-ion battery management systems where charging is inhibited below plus 5 degrees C to prevent lithium plating. It also appears in server inlet temperature monitors and HVAC controllers where a low-cost, no-external-component temperature switch in a 3-pin SOT-23-5 footprint is preferred over a full digital temperature-sensor IC.
