G752

Global Mixed-mode Technology

High Accuracy Digital Temperature Sensor and

Thermal Watchdog with Two-Wire Interface

Features

General Description

SMBus interface

Programmable Trip Point (T_OS) and Hysteresis

(T_HYST

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.

)

Separate open-drain output pin operates as

interrupt or comparator at output

Power up defaults permit stand-alone opera-

tion as thermostat

Shutdown mode to minimize power consump-

tion

Up to 8 G752s can be connected to a single bus

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_HYSTregisters. 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_HYSTfor

G752-2.
