PROC reverse polarity test?
I was wondering if anyone, including Cypress, has determined the result of a reverse-polarity supply on a PROC BLE chip or module?
A product using a CR2032 battery will usually have a possibility of the user inserting the battery backwards. Designing a polarity protection circuit with a very low voltage drop presents a challenge.
I do know from testing that "another well-known manufacturers" bluetooth chip will have a damaged radio if this happens although the CPU will still work.
