7.3.4 Overtemperature Protection

UCC25600 continuously senses its junction temperature. When its junction temperature rises above 160°C, the device will enter overtemperature protection mode with both gate drivers actively pulled low. When junction temperature drops below 140°C, gate driver restarts with soft start.
