Capacitive touch controllers

25 November 2009 Analogue, Mixed Signal, LSI

IDT has announced the availability of the newest members of the PureTouch family of capacitive touch devices – the first devices announced since IDT acquired the technology in June this year. Targeting computing, white goods and portable devices, the technology can be implemented through button, slider and scroll options.

The LDS6100 touch controller family is designed for low power consumption and enables power-efficient continuous scan of buttons without sleep modes, making it a suitable solution for battery-driven portable applications. In continuous scan mode, the device consumes only 125 μW, 15% lower than the current product family. With wide voltage range support (1,8 to 5,5 V d.c.), no external voltage converter is required for non-portable applications. The LDS6100 family offers support for a variety of industry standard interfaces, including I²C, SPI and SMBus.

The integrated LED drivers in the LDS6100 family allow automatic, instant visual feedback when a touch occurs, with built-in lighting options such as dimming, blinking and heartbeat-like effects. This implementation helps simplify the design by relieving the host processor from having to manually activate the LED drivers and eliminating the need for software-generated lighting effects. The LDS6100 also features direct communication mode (DCM), which assigns a status pin to each capacitive sensor, enabling touch buttons to perform like mechanical buttons, simplifying implementation in white goods applications.
