Temperature Monitoring

Datasheet

PRODUCT FEATURES

GENERAL DESCRIPTION

FEATURES

Automatic Beta Compensation

Resistance Error Correction

The EMC2101 is an SMBus 2.0 compliant, integrated

fan control solution complete with two temperature

monitors, one external and one internal. Each

temperature channel has programmable high limits that

can assert an interrupt.

Self-programming with available SMBus compatible

EEPROM

Selectable PWM or DAC fan driver output

The fan drive is selectable as a Pulse Width Modulator

(PWM) or Linear (DAC) output. The fan control output,

whether the PWM or DAC drive circuit, uses an eight

position look-up table to allow the user to program the

fan speed profile based on temperature. The DAC out-

put ranges from 0V to V_DDwith up to 6 bit resolution

while the PWM output has a range of 0% to 100% with

up to 64 steps.

Temperature Monitors

— External channel ±1°C accuracy

— Internal channel ±2°C accuracy

3.3 Volt Operation (5 Volt Tolerant Input Buffers)

SMBus 2.0 Compliant Interface, supports TIMEOUT

8-Pin MSOP Lead-free RoHS Compliant Packages

8-Pin SOIC Lead-free RoHS Compliant Package

The EMC2101 has an option to automatically upload the

contents of an attached SMBus compatible EEPROM for

auto-programming upon power up.

APPLICATIONS

Graphics Processors

Advanced thermal sensing enables reduced validation

and characterization time as well as accurately operat-

ing with smaller-geometry processors. Resistance Error

Correction (REC) automatically corrects the offset errors

of board trace and device resistance, up to 100Ω. Auto-

matic Beta Compensation allows the user the flexibility

to design applications that include processor substrate

transistors.
