Datasheet Microchip EMC2302 — Datenblatt

EMC2302 Dual RPM-Based PWM Fan Controller PRODUCT FEATURES Datasheet General Description Features The EMC2302 is an SMBus compliant fan controller with
up to two 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
an interrupt. В„ Additionally, the EMC2302 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„ SMBus 2.0 Compliant В„ CLK Pin can provide a clock source output
