0 Compliant: - Up to 6 selectable SMBus addresses for the EMC2303/5 - SMBus Alert compatible • CLK Pin Can Provide a Clock Source Output • EMC2301 Available in an 8-Pin MSOP Lead-Free RoHS Compliant Package • EMC2302 Available in a 10-Pin MSOP Lead-Free RoHS Compliant Package • EMC2303 Available in a 12-Pin 4 mm x 4 mm QFN Lead-Free RoHS Compliant Package • EMC2305 Available in a 16-Pin 4 mm x 4 mm QFN Lead-Free RoHS Compliant Package General Description The EMC2301/2/3/5 family is an SMBus compliant fan controller with up to five independently controlled PWM fan drivers.
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.
Additionally, the EMC2301/2/3/5 devices offer a clock output so that multiple devices may be chained as clients to the same clock source for optimal performance in large distributed systems.
