General Description
The G752 is a temperature sensor, Delta-Sigma ana-
log-to-digital converter, and digital over- temperature
detector with SMBus interface. The host can query
the G752 at any time to read temperature. The
open-drain Over temperature Shutdown (O.S.) output
becomes active when the temperature exceeds a
programmable limit. This pin can operate in either
“Comparator” or “Interrupt” mode.
The host can program both the temperature alarm
threshold (T_OS) and the temperature at which the
alarm condition goes away (T_HYST). In addition, the
host can read back the contents of the G752’s T_OS
and T_HYST registers. The sensor powers up in Com-
parator mode with default thresholds of 50°C T_OS
45°C T_HYST. for G752-1 and 80°C T_OS , 75°C T_HYST for
G752-2.
