GENERAL DESCRIPTION The ADT74701 controller 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 I2C? 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) APPLICATIONS Servers Networking and telecommunications equipment Desktops |
