Abstract
Systems, methods, and devices provide protection for sensing circuits. Methods may include providing, using a microcontroller unit (MCU), a drive signal to a touch sensor via an asymmetric conductance element of a protection circuit, providing, using the MCU, a scanning signal to the touch sensor via an additional conductance element of the protection circuit, and receiving, at the MCU, a sense signal from the touch sensor via the additional conductance element of the protection circuit. Methods also include determining, using the MCU, if a touch event has occurred based on measurements obtained during scanning of the touch sensor.
