RTS501-1B2B FAN CONTROLLER Features - Three wind modes can be selected: - Constant -Speed-Wind - Rhythmical Wind - Sleep-Wind - 3.5V to 4.3V power supply - Low power consumption - Three wind grades for each wind mode: - Soft, Medium, and Strong wind - Two timing functions - Summable - Non-summable General Description The RTS501-1B/2B is a CMOS LSI designed for fan controllers. In rhythmical wind mode, the wind speed is programmable; for example, it has programming options, to be soft -- medium - strong -- soft etc.. In sleep wind mode, the wind speed automatically decreases to help fall asleep. If any key is held for over 6 seconds, the RTS501-1B/2B will automatically power Off. If any two keys are simultaneously pushed, neither of the corresponding functions will be activated.
