If the junction temperature reaches the threshold of +140

⁰C, AP3790 shuts down immediately. Before VCC voltage decreases to UVLO, if the

junction temperature decreases to +100

⁰C, AP3790 can recover to normal operation. If not, the power system enters restart Hiccup mode until

the junction temperature decreases below +100

⁰C.
