A low power programmable capacitance-to-digital converter Power-On Touch Detection (CDC) supports up to 8 touch sensor inputs. Detect touch event upon power up without worry of sensors calibrating out fingers The touch inputs are directed through an integrated switch matrix to a sigma-delta CDC which senses changes in the external sensor array. When a change in capacitance occurs that is larger than the user defined threshold, a touch event is recognized and the host processor is notified via an interrupt pin. On-chip calibration logic continuously monitors the environment and automatically adjusts touch sensitivity to ensure robust performance. Proprietary noise-filtering algorithms may also be acti- vated to prevent false sensor activation in noisy system environments. The LDS6200 family offers 2 an I C compatible interface. A general-purpose input/output (GPIO) and an interrupt output are also provided for additional communication with the host processor. 2 * I C with no active reads + IDT THE ANALOG DIGITAL COMPANY LDS6200 PRODUCT FAMILY OVERVIEW 1Switch Matrix PureTouch Low Channel Capacitance Touch IC Family IntegratedDeviceTechnology POWER MANAGEMENT ANALOG & RF INTERFACE & CONNECTIVITY CLOCKS & TIMING MEMORY & LOGIC TOUCH & USER INTERFACE VIDEO & DISPLAY AUDIO LDS6200 Touch Family - Ideal Solution BENEFITS for Portable and Green Applications Ease-of-use and flexible configurability The LDS6200 is optimized for ultra-low power consumption. In full power mode, sensor con- with optimized, state machine architecture version and calibration occur continuously, minimizing the time between touch event and Longer battery life enabled with ultra-low touch detection. With its ultra- low touch sensor current consumption of <55 A (typical at power consumption 1.8V), the LDS6200 products may be operated continuously in full power mode, eliminating the Low BOM cost and minimized solution need for introduced latencies that can cause noticeable delays and degrade the user experi- footprint using bare minimum of external ence. Where power consumption is of the utmost importance, low power modes with con- components figurable latencies may be utilized to further reduce current below 20 A (100ms sleep cycle). Robust touch performance via proprietary The LDS6200 family is optimized for a minimized solution footprint, with the functionality of noise-filtering algorithms multiple components consolidated into a single device and a bare minimum of required exter- nal passive components.
