DESCRIPTION

· The LDS6200 Family of capacitive touch controllers streamlines human-machine interfaces by replacing mechanical inputs with touch-based controls like buttons, sliders, and scroll wheels.
· Utilizes a sigma-delta capacitance-to-digital converter and noise-filtering algorithms to reliably detect small capacitance changes.
· Features on-chip automatic calibration to adapt to environmental changes such as temperature, humidity, and dust.
· Comprises four products with up to 8 capacitive sensor input pins, supporting 1.65 to 5.5V supply voltages.
· Offers I2C compatible serial interfaces, GPIO, and VDDIO support for flexible voltage interfacing.
· Available in 3mm x 3mm 16-pin and 20-pin TQFN, as well as 16-pin and 20-pin SOIC packages.

FEATURES

· Supports up to 8 touch sensor channels with a 2ms update rate per active sensor.
· Includes built-in slider/scroll support and configurable hysteresis and debounce settings.
· Offers touch preference modes and operates at a supply voltage of 1.65-5.5V.
· Low touch sensor operating power with full power mode typically less than 125uW.
· Optional low power mode and on-chip automatic calibration algorithm.
· I2C compatible serial interface with VDDIO, power on touch detection, and configurable proximity sensing.
· GPIO and interrupt output available in compact 3mm x 3mm TQFN and SOIC packages.

APPLICATIONS

· Mobile handsets, personal media players, and portable navigation devices.
· Remote controls, office equipment, and multi-function printers.
· Set top boxes, home appliances, brown goods, and industrial controls.
