4马克斯约220毫秒的响应时间低功率模式@VDD = 3 v
5灵敏度可以调节的电容(1 ~ 50 pf)外面
6稳定的人体触摸检测取代传统直接切换键
7提供低功耗模式
8提供了直接输出或输出切换选择垫选项(衣服销)
9问销CMOS输出可以选择积极高垫或活性低的选项(AHLB销)
10准时的*大16秒吗
11在接通电源的大约0.5秒稳定时间,期间请勿触摸键垫,
和功能是禁用的
12汽车终身校准
re-calibration时期大约是1秒开机后8秒内。当关键是
感动在8秒内或关键不触及逾8秒开机后,然后
re-calibration时间更改到4秒

FEATURES
? Operating voltage 2.4V~5.5V
? Built-in regulator for touch sensor
? TTP233B-HA6 Operating current @VDD=3V, no load
At low power mode typical 2.5uA, maximum 5uA
? The response time max about 220mS at low power mode @VDD=3V
? Sensitivity can adjust by the capacitance(1~50pF) outside
? Stable touching detection of human body for replacing traditional direct switch key
? Provides Low Power mode
? Provides direct output or toggle output selection by pad option(TOG pin)
? Q pin is CMOS output can be selected active high or active low by pad option(AHLB pin)
? Have the maximum on time 16 sec
? After power-on have about 0.5 sec stable-time, during the time do not touch the key pad,
And the function is disabled
? Auto calibration for life
The re-calibration period is about 1 sec within 8 sec after power-on. When key has be
touched within 8 sec or key has not be touched more than 8 sec after power-on, then the
re-calibration period change to 4 sec.
