MS8885 suits keypad, matrix & slider applications up to 8x8 matrix (2 chips cascaded). Product highlights are ultra-low 10µA power consumption (sleep mode <100nA), easy implementation via dedicated I2C interface and small size bare die form factor.
Features:
- Dynamic 8-Channel proximity sensor switch
- Support for matrix arrangement of sensors
- Direct and latching switch modes
- Digital processing method with continuous auto calibration
- Sensing plates can be connected remotely
- I2C Fast-mode Plus (Fm+) compatible interface
- Interrupt output
- Clock and interrupt cascading for two ICs possible
- Address LSB can be configured via external pin (two ICs can be addressed)
- Low-power battery operation possible (IDD ~10µA)
- Sleep mode lower than 100nA
- Adjustable response time and sensitivity
- Large voltage operating range (VDD = 2.5 to 5.5V)
- Internal voltage regulator
Applications:
- Hermetically sealed keys on a keyboard
- Switch for medical applications
- Switch for use in explosive environments
- Vandal proof switches
- Automotive: Switches in or under upholstery,leather, handles, mats and glass
- Portable entertainment units
- Buildings: Switch in or under carpets, glass or tiles
- Sanitary applications: Use of standard metal sanitary parts (e.g. tap) as switch.
