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
