PRODUCT FEATURES

EMC2113

RPM-Based Fan Controller with Multiple Temperature

Zones & Hardware Thermal Shutdown

General Description

The EMC2113 is an SMBus compliant fan controller.

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.

The EMC2113 includes a temperature monitor that

measures up to three (3) external diodes and the

internal diode. 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.

The device includes high and low limits for all

temperature channels as well as a hardware set critical

temperature limit. This hardware set limit drives a

dedicated system shutdown pin.

Finally, the device includes an open-drain, active low

interrupt pin to flag temperature or fan control errors.
