TC6501/2/3/4 are temperature switch products produced by Microchip Technology Inc. They have a 5-pin SOT-23A package, preset temperature thresholds, and selectable temperature hysteresis. They are suitable for applications such as thermal management in personal computers and servers, over-temperature fault protection circuits, fan controllers, temperature alarms, projectors/printers, laptops, and network equipment.
The TC6501‑TC6504 family are ultra‑small temperature‑sensor ICs offered in a 5‑lead SOT‑23A package. They provide programmable temperature limits with hysteresis options and low quiescent current, making them suitable for high‑integration, low‑cost designs.
The document details pin assignments, supply voltage ranges, operating and storage temperature limits, typical performance curves, and recommended external components such as pull‑up resistors. Application notes describe how to use the devices for temperature monitoring, alarm generation, and control of external circuitry. This manual is written in Japanese.
