2 System Board

The Input/Output Controller Hub 2 (82801BA)

MaxiLife Architecture The MaxiLife chip continuously monitors temperature and voltage sensors located in critical regions on the system board. This chip receives data about the various system components via a dedicated I2C bus, which is a reliable communications bus to control the integrated circuit boards.
