EMC2303 Multiple RPM-Based PWM Fan Controller
for Three Fans
PRODUCT FEATURES Datasheet General Description Features The EMC2303 is an SMBus compliant fan controller with
up to three 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. В„ The closed loop Fan Speed Control algorithm (FSC) has
the capability to detect aging fans and alert the system.
It will likewise detect stalled or locked fans and trigger
Additionally, the EMC2303 offers a clock output so that
multiple devices may be chained and slaved to the
same clock source for optimal performance in large
distributed systems. вЂ”
