Microchip公司的EMC1815是多路低电压遥控二极管温度传感器,具有±1℃的精度,工作温度-40℃到 +125℃,温度传感器分辨率0.125℃,SMBus/I2C兼容接口(高达400 kHz),工作电压1.62V-3.6V,主要用在温度敏感的存储,工业,低系统电压的IoT,手持设备和手持游戏机以及计算和食物存储.本文介绍了EMC1815系列主要特性,功能框图,系统框图以及EMC1833评估板主要特性,框图,电路图,材料清单和PCB设计图.

The EMC1812/13/14/15/33 devices monitor one internal diode and up to four externally-connectedtemperature diodes.

Thermal management is performed in cooperation with a host device. This consists of the host readingthe temperature data of both the external and internal temperature diodes of the EMC1812/13/14/15/33and using that data to manage thermal events or to control the speed of one or more fans.

This device family introduces rate of change temperature measurement with associated alerts. Thisprovides a preemptive system alert and another protective measurement layer to catch and managevariable system temperatures. Resistance Error Correction automatically eliminates the temperature errorcaused by series resistance. This feature allows for routing long traces and off-board connections withwires, if desired. Automatic beta compensation eliminates the need for substrate diode and transistorconfigurations.
