TPS2549-Q1: Thermal Cycling

Part Number: TPS2549-Q1

Hi,

We got a question from customer about TPS2549-Q1.
Could you help us?

[Question]
Our customer would like to make sure about datasheet figure 23 Thermal cycling. Regarding figure 23, the IC continues turn-on and off. Is this behavior due to the thermal sensing which mean Tj reaches 135C then the IC turn-off, and Tj cools to 20C then the IC turn-on?

Best Regards,
tateo
