PRODUCT FEATURES

General Description

Features

Programmable Fan Control circuit.

The EMC2105 is an SMBus compliant fan controller with

up to five (up to 4 external and 1 internal) temperature

channels. The fan driver can be operated using two

methods each with two modes. The methods include an

RPM based Fan Speed Control Algorithm and a direct

drive setting. The modes include manually programming

the desired settings or using the internal programmable

temperature look-up table to select the desired setting

based on measured temperature.

—

600mA, 5V, High Side Fan Driver

—

Optional detection of aging fans

RPM based fan control algorithm

—

2% accuracy from 500RPM to 16k RPM

Temperature Look-Up Table

—

Allows programmed fan response to temperature

1 to 4 thermal zones to control fan driver

Controls fan speed or drive setting

Allows externally generated temperature data to control

fan drivers including two DTS channels

The temperature monitors offer 1°C accuracy (for

external diodes) with sophisticated features to reduce

errors introduced by series resistance and beta variation

of substrate thermal diode transistors commonly found

in processors.

Up to Four External Temperature Channels

—

Designed to support 45nm, 60nm, and 90nm CPUs

Automatically detects and supports CPUs requiring the

BJT or Transistor models

—

Resistance error correction

1°C accurate (60°C to 100°C)

0.125°C resolution

Detects fan aging and variation

The EMC2105 also includes a hardware programmable

temperature limit and dedicated system shutdown

output for thermal protection of critical circuitry.

Up to three thermistor compatible voltage inputs

Hardware Programmable Thermal Shutdown

Temperature

Applications

Notebook Computers

Embedded Applications

Projectors

—

Cannot be altered by software

—

60°C to 122°C Range or 92°C to 154°C Range

Programmable High and Low Limits for all channels

3.3V Supply Voltage

Industrial and Networking Equipment

SMBus 2.0 Compliant

—

SMBus Alert compatible

Available in 20-pin QFN Package - Lead Free RoHS

compliant (4mm x 4mm)
