In general, the protection circuits used with USB 2.0 will not be adequate to provide circuit protection for the new standard’s requirements for overcurrent and electrostatic discharge (ESD) threats.

One potential issue is that the USB Type-C is much smaller than USB Type-A. A USB Type-C connector has 24 pins with a 0.5-mm pitch, compared to the Type-A’s four pins with 2.5-mm pitch.

The circuit in this Design Ideacombines a mixed-signal microcontroller,a USB UART (universalasynchronous receiver/transmitter), anda novel adaptable analog sensor-inputcircuit. It allows you to ...
