TTP112-DOB : direct mode with active high, sop-16. ttp112-eob : pwm dim/ direct mode, toggle mode , sop-16. 2. ttp112 : pwm dim mode function (1). touch (switch) mode a. short touch(switch) inpu t mode (light on/off) - in normal speed (nssel=0): when touch time is less then 0.3 second. - in slow speed (nssel=1): when t ouch time is less then 0.6 second. b. long touch(switch) mode (continuous dimming) - in normal speed (nssel=0): when touch time is more then 0.3 second. - in slow speed (nssel=1): when t ouch time is more then 0.6 second. c. in touch mode can auto stop dimming, when di mming over most lightness 4 times then stop dimming luminance automatically. (2). two modes of turn off: non-delay off and delay off by option sel a. non-delay-off mode (sel=0): if lamp is on, s hort touch lamp will turn off. short touch again lamp will be turn on. b. delay-off mode (sel=1): if lamp is on, short touch will cause the lightness to be dark slowly, until the lightness become the darkest and keep the lightness, then turn off. c. the total delay off time is about 18 seconds. d. during delay off time, the lamp will be turn off immediately when touch again. (3). long touch or push switch about buzzer a. cycle mode 1. a long touch or push switch will adjust the lightness, during adjust ing the lightness. the lightness will change from bri ght to dark and from dark to bright continuously. stopping long touch or push switch, the lamp will keep the lightness. 2. there is ?bi-bi? sound from buzzer when it will approach the highest lightness, and stop adjusting lightness. it will reach the highest lightness. 3. a lightness cycle of normal speed-dim is about 6 seconds. slow speed-dim is about 12 seconds. b. non-cycle mode 1. a long touch or push switch will adjust th e lightness, when appro ach the highest lightness will stop adjusting the lightness. and ?bi-bi? sound from buzzer. 2. a long touch or push switch will adjust th e lightness, when approach the darkest lightness will stop adjusting the lightne ss. buzzer is soundless. c. buzzer frequency is about 4.0khz. (4). memory function a. when lamp is turned on every time , the lightne ss is the same as the last turn off lightness. if the lamp is delay off, the lamp will be turn on with the lightness that the lamp before become delay off mode. b. when ac power is supplied at first time, the lamp is turn on with the highest lightness.
