ADT7470ARQZ Description

Short technical summary and product information.

The ADT7470ARQZ from Analog Devices is a multichannel temperature sensor and PWM fan controller designed for systems requiring active cooling. It interfaces directly to an I2C bus, allowing for monitoring and control of system temperatures and fan speeds.

 

This controller can monitor up to 10 remote temperature sensors and independently control the speed of up to 4 fans. It supports a fast I2C standard up to 400 kHz and meets SMBus 2.0 electrical specifications. The device operates over a voltage range of 3V to 5.5V and has an operating temperature range of -40°C to 125°C.

 

Key features include PWM outputs for fan control, a FULL_SPEED input for external hardware control, and an SMBALERT interrupt for signaling failures like fan underspeed or over-temperature conditions. The ADT7470ARQZ is available in a 16-QSOP and 16-SSOP package, suitable for surface mount applications.

 

Applications for this IC include servers, networking equipment, telecommunications equipment, and desktops where precise thermal management is crucial.
