Product Description
The I²C temperature sensor can be accessed through the 10 pin FRC connector from the motherboard. The temperature sensor can measure the local IC temperature, and a remote temperature. For measuring remote temperatures a transistor connected to the REMOTE SENSOR port is used as the sensing element. An alert interrupt is raised when the temperature exceeds a configurable set point. The signal T_CRIT is raised when the temperature exceeds a configurable critical set point. This is useful for automatic temperature regulation applications, where the system is to be shutdown or a fan is to be switched ON , without software intervention. The board provides a isolated 12V/1Amp power switch. The board switches ON the 12V/1Amp DC OUT on T_CRIT assertion and switches OFF the DC OUT on T_CRIT de-assertion. DC OUT can be connected to a 12V fan to switch it on and off automatically on thermal critical points.
Board Features
• SA56004 , I²C temperature sensor
