TPS92630-Q1: TPS92630-Q1 Thermal Foldback programming

Part Number: TPS92630-Q1

Hello,

I cannot understand what the below line at the bottom of p.19 of the datasheet means. What does this mean?

"With TEMP floating, the definition of thermal monitor activation temperature, T(th), is the temperature at which the current reduction begins."

What if without floating? I guess the definition is still the same.

I would also like to know if TEMP can be left floating.

Thanks.

  • Thermal foldback temperature threshold has relationship with the configuration on TEMP pin. Detailed please refer to figure 25 in the datasheet. If temp pin is in floating state the T(th) will be typically 110C which can be found in the electrical table.
