Datasheet Microchip EMC2301 — Datenblatt

EMC2301 RPM-Based PWM Fan Controller PRODUCT FEATURES Datasheet General Description Features The EMC2301 is an SMBus compliant fan controller with
a PWM fan driver. The 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„ Each 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 an interrupt.
Additionally, the EMC2301 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. В„
