FEATURES
SM3015 is a multi-function Fan Controller CMOS
IC that can be applied to a variety of consumer
products. It has an elastic function like MCU but
does not need programming, user can just write a
MASK form.
* High performance CMOS technology.
* Rhythm wind or Normal wind for SLEEP
mode can be chosen.
* Two to three-wind grade control in wind
modes.
SM3015 has three or four wind modes; normal,
rhythm and sleep-rhythm wind or normal, rhythm,
sleep-normal and sleep-rhythm, the operation
pattern of rhythm and sleep modes can be set by
user.
Many kinds of timer setting and two swing head
control that include micro-swing output can be

Memory or non-memory function is available; the
Speed, Mode, Swing functions will operate as last
state in memory type.
* Memory start-up function option.
* Many types of timer setting on three or four
steps and ladder adder or non-ladder
adder.
* Two swing head control, micro-swing output
can be chosen by MASK option.
* SPEED or ON/OFF key can enable fan
controller.
* 16 or 32 patterns per cycle of rhythm/sleep
mode, each pattern has 2.5 sec.
* Panel control or pair with SM5021B for an
infrared Remote Fan Controller.
* 16/18/20/22 pin plastic DIP package.
* 32.768KHz/455KHz oscillator option.
Supports two-bit customer codes to distinguish
different models.
