Product Description

The ADT7470ARQZ is a Temperature Sensor Hub and Fan Controller for systems requiring active cooling. It is designed to interface directly to an I²C® bus. It 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. A FULL_SPEED input is provided to allow the fans to be blasted to maximum speed, via external hardware control, under extreme thermal conditions or on system start-up. An SMBALERT interrupt communicates error conditions such as fan under speed and over-temperature measurements to the system service processor. Individual error conditions can then be read from status registers over the I²C bus.
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 (400kHz maximum)
ESD sensitive device, take proper precaution while handling the device.
