The MAX2140 SDARS receiver can experience internal ESD diode failure during a hot-plug operation, which is not a standard operation for this device. While this can occur in many applications, hot-plugging is a high probability in the automotive industry. This application note reviews the cause of the ESD diode problem during hot-plug, and helps calculate and properly design the circuitry to prevent the failure.
