G753

Global Mixed-mode Technology

High Accuracy Digital Temperature Sensor and

Thermal Watchdog with Two-Wire Interface

Features

General Description

SMBus interface

The G753 is a temperature sensor, analog-to-digital

converter, and digital over- temperature detector with

SMBus interface. The host can query the G753 at any

time to read temperature. The open-drain ALERT#

output becomes active when the temperature ex-

ceeds a programmable limit which initialed by hard-

ware power-on setting. This pin can operate in either

“Comparator” or “Interrupt” mode.

Hardware Power-on Setting & Programmable

over temperature limit

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

Applications

System Thermal Management

Personal Computers

Office Electronics
