The Failure Mode and Effect Analysis (FMEA) Implementation for CSD
This application note describes functions that allow you to perform run-time sensor diagnostics in CSD based designs. These functions detect sensor line shorts to Vcc or ground, sensor-to-sensor shorts, and modulator component faults. They also detect when sensor pads are disconnected. Sensors with specific critical-safe requirements such as On/Off buttons can be implemented with hardware redundancy.
