Product Overview

EMC2301-1-ACZL-TR is a single RPM-based PWM fan controller. Each fan driver is controlled by a programmable frequency PWM driver and fan speed control algorithm that operates in either a closed loop fashion or as a directly PWM-controlled device. Each closed loop fan speed control (FSC) algorithm has the capability to detect aging fans and alert the system. It will likewise detect stalled or locked fans and trigger an interrupt. This device offers a clock output so that multiple devices may be chained as clients to the same clock source for optimal performance in large distributed systems. Application includes servers, projectors, industrial and networking equipment, notebook computers.
  • Up to five programmable fan control circuits, 4-wire fan compatible
  • High-speed PWM (26KHz), low-speed PWM (9.5Hz to 2240Hz)
  • 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 500RPMto16kRPM (external crystal oscillator), 1% accuracy from 500RPM to 16kRPM
  • Up to 6 selectable SMBus addresses for the EMC2303/5, SMBus Alert compatible
  • CLK pin can provide a clock source output
  • Supply voltage range from 3 to 3.6V (VDD = 3.0V to 3.6V, TA = +27°C)
  • MSOP-8 package
