MIC281-1BM6中文资料麦瑞半导体数据手册PDF规格书

General Description

The MIC281 is a digital thermal sensor capable of measuring the temperature of a remote PN junction. It is optimized for applications favoring low cost and small size. The remote junction may be an inexpensive commodity transistor, e.g., 2N3906, or an embedded thermal diode such as found in Intel Pentium* II/III/IV CPUs, AMD Athlon* CPUs, and Xilinx Virtex* FPGAs.

特性 Features

• Remote temperature measurement using embedded thermal diodes or commodity transistors
