ADT7470ARQ-REEL7 FEATURES

Monitors up to 10 remote temperature sensorsMonitors and controls speed of up to 4 fans independentlyPWM outputs drive each fan under software controlFULL_SPEED input allows fans to be blasted to maximumspeed by external hardwareSMBALERT interrupt signals failures to system controllerThree-state ADDR pin allows up to 3 devices on a single busTemperature decoder interprets TMP05 temperature sensorsand communicates values over I2C busLimit comparison of all monitored valuesSupports fast I2C standard (400 kHz max)Meets SMBus 2.0 electrical specifications(fully SMBus 1.1-compliant)

ADT7470ARQ-REEL7 GENERAL DESCRIPTION

The ADT74701 controller is a multichannel temperature sensorand PWM fan controller and fan speed monitor for systemsrequiring active cooling. It is designed to interface directly toan I2C® bus. The ADT7470 can monitor up to 10 daisy-chainedTMP05 temperature sensors. It can also monitor and controlthe speed of four fans, in automatic or in manual control loops.A FULL_SPEED input is provided to allow the fans to beblasted to maximum speed, via external hardware control,under extreme thermal conditions or on system startup. AnSMBALERT interrupt communicates error conditions such asfan under speed and over temperature measurements to thesystem service processor. Individual error conditions can thenbe read from status registers over the I2C bus.
