The MCP9501/2/3/4 modules are temperature switches with a threshold of ± 1°C (typically). These modules are ideal for supply voltage systems in which a protection circuit against overheating is required. They require no external components and consume 25 µA of power. https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2017-08-06 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2018-02-24 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2018-05-04 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2018-12-18 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2019-04-02 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2021-05-22 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2021-12-17 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2022-05-18 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2023-11-25 https://elecena.pl/product/9717721/mcp9504pt-005e-ot-temperature-switch-5-c-sot-23-5 2024-04-16
