PRODUCT FEATURES

EMC6D103

Fan Control Device with

High Frequency PWM

Support and Hardware

Monitoring Features

3.3 Volt Operation (5 Volt Tolerant Input Buffers)

SMBus 2.0 Compliant Interface (Fixed, not

Discoverable) with Three Slave Address Options

Fan Control

— PWM (Pulse width Modulation) Outputs (3)

— Fan Tachometer Inputs (4)

— Programmable automatic fan control based on

temperature

— Backwards compatible with fans requiring lower

frequency PWM drive

— High frequency fan support for 4 wire fans

— One fan can be controlled from as many as 3

temperature zones

— Fan ramp rate control for acoustic noise reduction

Power Savings Modes

— Two monitoring modes: continuous or cycling (for power

savings)

— Two low power modes when monitoring if off: Sleep and

Shutdown

Temperature Monitor

— Monitoring of Two Remote Thermal Diodes (+/- 3 deg

C accuracy)

— Internal Ambient Temperature Measurement

— Limit Comparison of all Monitored Values

— Interrupt Pin for out-of-limit Temperature Indication

— Configurable offset for internal or external temperature

channels.

Voltage Monitor

— Monitor Power supplies (+2.5V, +5V, +12V, Vccp, and

VCC)

— Limit Comparison of all Monitored Values

— Interrupt Pin for out-of-limit Voltage Indication

5 VID (Voltage Identification) Inputs

XOR Tree Test Mode

24-Pin, SSOP Lead-Free RoHS Compliant Packages
