General Description
The G751 is a temperature sensor, Delta-Sigma
analog-to-digital converter, and digital over- tem-
perature detector with SMBus interface. The host
can query the G751 at any time to read temperature.
The open-drain Over temperature Shutdown (O.S.)
output becomes active when the temperature ex-
ceeds a programmable limit. This pin can operate in
either “Comparator” or “Interrupt” mode.
The host can program both the temperature alarm
threshold (TOS) and the temperature at which the
alarm condition goes away (THYST). In addition, the
host can read back the contents of the G751’s TOS
and THYST registers. The sensor powers up in Com-
parator mode with default thresholds of 50°C TOS
45°C THYST. for G751-1 and 80°C TOS , 75°C THYST
for G751-2.
