LC717A30UR

LC717A30UR Capacitance‐Digital‐Converter LSI for Electrostatic Capacitive Touch Sensors The LC717A30UR is a high performance, low cost, and highly usable capacitance converter for electrostatic capacitive touch and proximity sensors. 8 capacitance-sensing input channels ideal for use in any end products that needs an array of switches. The LC717A30UR facilitates a short system development time through its automatic calibration function and minimal external components. The detection result (ON/OFF) for each sensor is read out by the serial interface (I2C or SPI). Features Differential Capacitive Detection Using Mutual Capacitance Operates with Small to Large Capacitance Sensor Input Pads Capacitance Detection Down to Femto-Farad Level Measurement Time 16 ms for 8 Sensors Minimal External Components Selectable Interface: I2C or SPI Current Consumption: 0.8 mA (VDD = 5.5 V) Supply Voltage: 2.6 V to 5.5 V AEC−Q100 Qualified and PPAP Capable Typical Applications Automotive: Smart Key, Control Switches, Car Audio, Proximity Consumer: Home Appliance, White Goods, Induction Cooking Industrial: Security Lock Computing: PC Peripherals, Audio Visual Equipment Lighting: Remote Control Switches www.onsemi.com Top View Bottom View VCT28 3.5 y 3.5 CASE 601AE MARKING DIAGRAM XXXXXXXX YMDDD XXXXX = Specific Device Code Y = Year M = Month DDD = Additional Traceability Data ORDERING INFORMATION See detailed ordering and shipping information on page 9 of this...
