Overview
Le Fan Click Board™ intègre un contrôleur EMC2301 pour alimenter et réguler le fonctionnement des ventilateurs à quatre fils 5 V, qui sont couramment utilisés comme refroidisseurs dans les ordinateurs et autres appareils électroniques.
IC/module: EMC2301 RPM-Based PWM Fan Controller
The EMC2301 module is a programmable fan control circuit designed for powering and regulating the operation of 5V four-wire fans. Controlled by a programmable frequency PWM driver and Fan Speed Control algorithm, it operates in either a closed loop fashion or as a directly PWM-controlled device. It has the capability to detect aging fans and alert the system. It is an ideal option for optimal performance in large distributed systems.
RPM-based Fan Speed Control Algorithm (FSC)
Fan Click Board™ includes a manually controlled RPM-based Fan Speed Control Algorithm. The FSC algorithm automatically approaches and maintains the systems required fan speed using Proportional, Integral, and Derivative terms. It provides accuracy directly proportional to the accuracy of the clock source.
Power Supply Selection
Fan Click Board™ is designed to use a 3.3V power supply only. However, the pins on the board are both 3.3V and 5V tolerant, and hence, it can use both logic levels.
