ASC7611 Product details

[Andigilog, Inc.]



Product Description

The aSC7611 has a two wire digital interface compatible with SMBus 2.0. Using a 10-bit ΣΔ- ADC, the aSC7611 measures the temperature of two remote diode connected transistors as well as its own die.

Using temperature information from these three zones, an automatic fan speed control algorithm is employed to minimize acoustic impact while achieving recommended CPU temperature under varying operational loads.

To set fan speed, the aSC7611 has three independent pulse width modulation (PWM) outputs that are controlled by one, or a combination of three, temperature zones. Both high- and low-frequency PWM ranges are supported.



Features

• 2-wire, SMBus 2.0 compliant, serial interface

• 10-bit ΣΔ-ADC

• Monitors internal and remote thermal diodes

• Monitors VCCP, 2.5V, 3.3V, 5.0V, and 12V motherboard/processor supplies

• Programmable autonomous fan control based on temperature readings

• Noise filtering of temperature reading for fan control

• 0.25°C digital temperature sensor resolution

• 3 PWM fan speed control outputs for 2-, 3- or 4- wire fans.

• Provides high and low PWM frequency ranges

• 4 fan tachometer inputs

• Monitors 5 VID control lines

• 24-Lead QSOP package

• XOR-tree test mode



Applications

• Desktop Computers – Motherboards and Graphics Cards

• Laptop Computers

• Microprocessor based equipment (e.g. Base stations, Routers, ATMs, Point of Sales)
