PRODUCT FEATURES

General Description

Features

Two Programmable Fan Control circuits

The EMC2106 is an SMBus compliant fan controller with

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

channels. The fan drivers 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.

—

4-wire fan compatible

High speed PWM (26khz)

Low speed PWM (9.5Hz - 2240Hz)

600mA, 5V, High Side Fan Driver

Optional detection of aging fans

1mA Linear DAC Fan Driver

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 each 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)

The EMC2106 also includes a hardware programmable

temperature limitS and dedicated system shutdown

output for thermal protection of critical circuitry.

—

Applications

0.125°C resolution

Notebook Computers

Embedded Applications

Projectors

Three dedicated comparator outputs for External

Diode 1, External Diode 2, and External Diode 3

(OVERT1#, OVERT2#, OVERT3#)

Industrial and Networking Equipment

Up to three thermistor compatible voltage inputs

Hardware Programmable Thermal Shutdown

Temperature

—

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

SMBus 2.0 Compliant

—

2 selectable SMBus addresses

SMBus Alert compatible

Option to load register set from external EEPROM

Available in 28-pin QFN package - Lead Free RoHS

compliant (5mm x 5mm)
