特性
1工作電壓2.4 v ~ 5.5 v
2內置調節器觸摸傳感器
3操作當前@VDD = 3 v,沒有負擔
在低功耗模式下典型2.5 ua,*大5 ua
4馬克斯約220毫秒的響應時間低功率模式@VDD = 3 v
5靈敏度可以調節的電容(1 ~ 50 pf)外面
6穩定的人體觸摸檢測取代傳統直接切換鍵
7提供低功耗模式
8提供了直接輸出或輸出切換選擇墊選項(衣服銷)
9問銷CMOS輸出可以選擇積極高墊或活性低的選項(AHLB銷)
10準時的*大16秒嗎
11在接通電源的大約0.5秒穩定時間,期間請勿觸摸鍵墊,
和功能是禁用的
12汽車終身校準
re-calibration時期大約是1秒開機后8秒內。當關鍵是
感動在8秒內或關鍵不觸及逾8秒開機后,然后
re-calibration時間更改到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. |
