The temperature warning signals at the TAS5352DDV6EVM board are wired-OR to one temperature
warning signal (OTW – pin 22 in control interface connector).
warning signal (OTW – pin 22 in control interface connector).
The shutdown signals are wired-OR into one shutdown signal (SD – pin 20 in control interface connector).
The shutdown signals together with the temperature warning signal give chip state information as
