SH1475

SH1475 Single-Axis Capacitive www.DataSheet4U.com Touch Sensor Controller HID & SYSTEM MANAGEMENT PRODUCTS DESCRIPTION The SH1475 single-axis capacitive touch sensor controller is a costeffective, single-dimension capacitive position analyzer with a full-duplex SPI® interface. The SH1475 is ideal for handheld devices such as MP3 players. The SH1475 uses an advanced algorithm for enhanced motion control interfacing PCB-based capacitive sensor. The SH1475 includes a signal conditioning circuit for a low cost, simple and real estate-saving implementation. Just a few additional low-tolerance external components are needed for a complete solution. Typically consuming about 1 µA in the standby state, the SH1475 is ideal for battery-operated systems. FEATURES Full-duplex SPI Interface PCB-based capacitive sensor Five switches 2.7 V – 5.5 V Low power consumption: 1 µA in standby state (typical) Royalty-free and cost-effective Customization available Small 6 mm x 6 mm 36-lead MLPQ package PRELIMINARY APPLICATIONS Portable media players Portable media centers PIN ASSIGNMENTS Instruments Cell phones nSW3 nSW2 nSW1 nTxReq nSW5 nChipSelect E4 E5 NC THERMAL PAD CP SENSE CN FDA VREF nRST VSS2 VDD NC www.semtech.com 27 28 19 18 nSW4 nWakeUp MOSI MISO SCLK WAKE SWPWR RINT AD 36 1 NC E6 E1 E2 E3 VSS XOUT XIN NC 10 9 Semtech, the Semtech logo, and Self-Power Management are marks of Semtech Corporation.
