General Description

The G751 is a temperature sensor, Delta-Sigma analog-to-digital converter, and digital over- temperature 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 exceeds a programmable limit. This pin can operate in either “Comparator” or “Interrupt” mode.
