General Description The G753 is a temperature sensor, analog-to-digital converter, and digital over- temperature detector with SMBus interface. The host can query the G753 at any time to read temperature. The open-drain ALERT# output becomes active when the temperature exceeds a programmable limit which initialed by hardware power-on setting. This pin can operate in either “Comparator” or “Interrupt” mode. Applications „ System Thermal Management „ Personal Computers „ Office Electronics „ Electronic Test Equipment.
