G751-1P1

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 (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 G751'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 G751-1 and 80°C T_OS , 75°C T_HYST for G751-2.
