This article describes a circuit design for a power conditioning circuit for an automotive vehicle touch controller. Automotive requirements on the vehicle wiring harness dictate that all interfaces to the vehicle harness must be capable of withstanding a short to battery voltage (+12 volts) or ground, and should survive the effect of specific electrical transients. The circuit, disclosed herein, meets these requirements, providing improved performance and in creased reliability over existing designs because of protection against electrical transients and shorts to battery voltage and ground. This disclosure describes in detail the design of the power conditioning circuit for a touch controller. Fig.
