EMC2301 - PWM Fan Controller

Datasheet Summary

Description

The EMC2301/2/3/5 family is an SMBus compliant fan controller with up to five independently controlled PWM fan drivers.

Features

Up To Five Programmable Fan Control Circuits: - 4-wire fan compatible - High-speed PWM (26 kHz) - Low-speed PWM (9.5 Hz-2240 Hz) - Optional detection of aging fans - Fan Spin Up Control and Ramp Rate Control - Alert on Fan Stall - Up to three selectable default fan speeds for the EMC2303/5.
Watchdog Timer.
RPM-Based Fan Control Algorithm: - 0.5% accuracy from 500 RPM to 16k RPM (external crystal oscillator) - 1% accuracy from 500 RPM to 16k RPM (internal clock).
