三合微科股份有限公司 SAMHOP Microelectronics Corp. SM3501 FAN CONTROLLER GENERAL DESCRIPTION SM3501 is a Fan Controller CMOS IC, has three wind modes; normal, rhythm and sleep wind. Four kinds of timer setting and a toggled O/P that can be used as swing/light. Memory function is available; the Speed, Mode, Swing functions will operate as last state; if last state is Sleep mode, press SPEED or ON/OFF key enable fan controller while memory functions( Speed / Mode / Swing ) will be returned to the last state before sleep mode operation. FEATURES * High performance CMOS technology * 455KHz or RC type can be selected. * Two to three wind modes can be selected. Normal, Rhythm and Sleep wind mode. * Three-wind grade control in each wind mode: Low, Medium and Strong wind. * Four types of timer setting by PIN option: ladder adder (1/2 - 1 - 2 - 4 - 8HRS / 1 - 2 - 4HRS) non-ladder adder (1 - 2 - 4 - 8HRS / 1 - 2 - 4HRS) * SPEED or ON/OFF key can enable fan controller by PIN option APPLICATIONS * Electronic Fan * Heater Fan PIN ASSIGNMENT LOW TGO BUZ OSC1 OSC2 OPTION1 VDD SPEED TGI 1 2 3 4 5 6 7 8 9 SM3501 18 17 16 15 14 13 12 11 10 MID STR OPTION2 VSS COM2 COM1 MODE TIMER ON-OFF/OFF Page 1 V.2.0 Mar 8,2002 三合微科股份有限公司 SAMHOP Microelectronics Corp.

SM3501 FAN CONTROLLER FUNCTION DESCRIPTION SM3501 has five control signal operations: * Start-up by SPEED key a. function turn off ( OFF key ) b. wind mode select ( MODE key ) c. start-up function and wind speed select ( ON / SPEED key ) d. timer setting ( TIMER key ) e. swing head or light ( TGI key ) * Start-up by ON / OFF key a. function control ( ON / OFF key ) b. wind mode select ( MODE key ) c. wind spped select ( SPEED key ) d. timer setting ( TIMER key ) e. swing head or light ( TGI key ) Only SPEED or ON / OFF key can enable the fan controller ; wind mode, timer and swing head inputs can not be accepted when fan is not activated. The fan controller will be turned off by timer time out or OFF ( ON / OFF ) key inputs. When more than one key are pressed, controller will not accept the multi-key's control signal, if the panel keys are pressed more than six seconds, controller will generate a "Bi-Bi-Bi-Bi" warning sound. state of fan controller is as follows: * Memory function available If Fan controller is OFF on sleep mode, all memory functions will be returned to the LAST STATE BEFORE SLEEP MODE operation. a. grade as last state but with starting medium wind for three seconds b. the wind mode as last state except sleep mode c. swing function as last state d. timer setting off A. OFF KEY When fan controller is on, press the OFF key on panel, fan functions will be turned off. * PIN 6 OPTION1: ON / OFF KEY When fan controller functions are on, press ON / OFF key on panel, fun function will be turned off; if functions are off, press the key to turn on fan functions. Page 4 V.2.0 Mar 8,2002 三合微科股份有限公司 SAMHOP Microelectronics Corp. SM3501 FAN CONTROLLER B. SPEED KEY When fan controller is off, press SPEED key on panel, fan is turned on, initial state is LOW wind; when memory function is available, the wind grade will operate as last state. Both conditions there are three seconds startng wind. Press the SPEED key again, the wind will be changed as follows: OFF LOW MEDIUM STRONG :SPEED key used :Pluse is put into OFF pin * PIN 6 OPTION1: SPEED KEY ONLY If fan controller is off, SPEED key cannot be used, must press ON / OFF key to turn on the fan controller. When fan controller is on, press SPEED key on panel the wind grade changes as follows: OFF LOW MEDIUM STRONG :SPEED key used :Pluse is put into ON / OFF pin :SPEED or ON / OFF key used C. MODE KEY SM3501 has three types of wind mode key setting. Memory function is available except on sleep mode. OFF NOR RHY SLP :Press MODE key : normal setting :Pluse is put into OFF or ON / OFF pin :SPEED or ON / OFF key used Page 5 V.2.0 Mar 8,2002 三合微科股份有限公司 SAMHOP Microelectronics Corp. SM3501 FAN CONTROLLER * PIN 16 OPTION2: Two kinds of wind mode operation, these can be chosen by mode key setting. OFF NOR RHY :Press MODE key: normal setting :Pluse is put into OFF or ON / OFF pin :SPEED or ON/OFF key used D. TGI KEY The swing key will not activate when fan controller is off. Memory function is available, the swing output will operate as last state when press SPEED or ON / OFF key. OF F TGO enable : The TGI key press E. TIMER KEY SETTING SM3501 has many types of timer setting, mode A is ladder-adder and mode B is non-ladder adder for three or four steps. Timer key will not activate when fan controller is off. These types of timer may be chosen by MASK or BONDING option. F. BUZZER Any key pressed on panel or fan controller receives a control signal form remote control handset, will generate a 4KHz 50% duty cycle pulse train on buzzer output pin.
