In addition to the global OTW, each channel also has an individual overtemperature warning and shutdown. If a channel exceeds the OTW(i) threshold, the warning register bit is set as the WARN pin is asserted, unless the mask bit has been set to disable reporting. If the channel temperature exceeds the OTSD(i) threshold then that channel goes to the Hi-Z state until the temperature drops below the OTW(i) threshold. At this point, the channel goes to the state indicated by the state control register.
