Touch controllers consume little power

Building on other members of the PureTouch family, the LDS6200 series of touch controllers can detect up to eight simultaneous touches and includes built-in proximity sensing, which allows activation of features such as backlighting and wakeup prior to the actual touch contact. The family also features power-on touch detection, which solves the problem of end devices not recognizing existing touches during power on.

The family enables power-efficient continuous scan of buttons without sleep modes, making the LDS6200 an ideal solution for battery-driven portable applications. In continuous scan mode, the LDS6200 consumes only 100 µW. With voltage range of 1.8 to 5.5 Vdc, no external voltage converter is required for non-portable applications. Housed in 16- and 20-pin TQFN and SSOP packages, the controllers offer support for I2 C interface. ($0.70 ea/1,000 — available now.)
