GENERAL DESCRIPTION

The ADT7470¹controller is a multichannel temperature sensor and PWM fan controller and fan speed monitor for systems requiring active cooling. It is designed to interface directly to an I2CÂ® bus. The ADT7470 can monitor up to 10 daisy-chained TMP05 temperature sensors. It can also monitor and control the speed of four fans, in automatic or in manual control loops.

FEATURES

Monitors up to 10 remote temperature sensors
Monitors and controls speed of up to 4 fans independently
PWM outputs drive each fan under software control
FULL_SPEED input allows fans to be blasted to maximum speed by external hardware
SMBALERT interrupt signals failures to system controller
Three-state ADDR pin allows up to 3 devices on a single bus
Temperature decoder interprets TMP05 temperature sensors and communicates values over I2C bus
Limit comparison of all monitored values
Supports fast I2C standard (400 kHz max)
Meets SMBus 2.0 electrical specifications(fully SMBus 1.1-compliant)
