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 ex-
ceeds a programmable limit which initialed by hard-
ware power-on setting. This pin can operate in either
“Comparator” or “Interrupt” mode.
Applications
„ System Thermal Management
„ Personal Computers
„ Office Electronics
„ Electronic Test Equipment
