Fan controller design example
Description
The Fan Controller Design Example, based on an NXP P89LPC917 microcontroller, provides intelligent and flexible responsive control over five fans.
The fan controller may independently or simultaneously control the operation of multiple fans depending upon the environmental temperature.
The PWM and A/D functions of the P89LPC917 enable the design to realize multiple control curves in order to precisely control a multiple-fan system.
