8 / 24 page  EMC1001 DS20005411A-page 8 2015 Microchip Technology Inc. 4.0 PRODUCT DESCRIPTION The EMC1001 is an SMBus temperature sensor that monitors a single temperature zone. Thermal manage- ment is performed in cooperation with a host device. The host reads the temperature data from the EMC1001 and takes appropriate action such as con- trolling fan speed or processor clock frequency. The EMC1001 has programmable temperature-limit regis- ters that define a safe operating window. After the host has configured the temperature limits, the EMC1001 can operate as a free-running independent watchdog to warn the host of temperature hot-spots, without requiring the host to poll the device. The ADDR/THERM output can be used to control a fan without host intervention. FIGURE 4-1: Controlling a Fan without Host Intervention. The EMC1001 has two basic modes of operation: • Run Mode: In this mode, the EMC1001 continuously converts temperature data and updates its registers. The rate of temperature conversion is configured as shown in Section 4.9 “Conversion Rate Register”. • Standby Mode: In this mode, the EMC1001 is placed in Standby to conserve power, as described in Section 4.5 “Standby Mode”.
