EMC2103

RPM-Based Fan

Controller with HW

Thermal Shutdown

Datasheet

PRODUCT FEATURES

The EMC2103 is an SMBus compliant fan controller with

up to up to 3 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

PWM 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.

Features

Programmable Fan Control circuit

—

4-wire fan compatible

—

High and low frequency PWM

RPM based fan control algorithm

—

2.5% accuracy from 500RPM to 16k RPM

—

Detects fan aging and variation

Temperature Look-Up Table

—

Allows programmed fan response to temperature

Controls fan speed or PWM drive setting

Allows externally set temperature data to drive fan

Supports DTS data from CPU

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 Three External Temperature Channels

(EMC2103-2 only)

—

Supports 45nm, 60nm, and 90nm CPU diodes

Automatically detects and supports CPUs requiring BJT

or Transistor models

The EMC2103 also includes a hardware programmable

temperature limit and dedicated system shutdown

output for thermal protection of critical circuitry.

—

Resistance error correction

Supports discrete transistors (i.e. 2N3904)

1°C accurate (60°C to 125°C)

Applications

0.125°C resolution

Notebook Computers

Projectors

Hardware Programmable Thermal Shutdown

Temperature

—

Cannot be altered by software

Graphics Cards

—

65°C to 127°C Range

Industrial and Networking Equipment

Programmable High and Low Limits for all channels

Internal Temperature Monitor

—

2°C accuracy

—

0.125°C resolution

3.3V Supply Voltage

SMBus 2.0 Compliant

—

SMBus Alert compatible

Two dedicated GPIOs (EMC2103-2 and EMC2103-4

only)

Available in 12-pin, QFN Lead-Free RoHS Compliant

Package (EMC2103-1 and EMC2103-3) or 16-pin,

QFN Lead-Free RoHS Compliant Package

(EMC2103-2 and EMC2103-4)
