ZHCS779C March 2012 – July 2025 UCC28070 , UCC28070A
PRODUCTION DATA
To protect the power supplies from silicon failures at excessive temperatures, the UCC28070A has an internal temperature-sensing comparator that shuts down nearly all of the internal circuitry and disables the GDA and GDB outputs if the die temperature rises above 160°C. Once the die temperature falls below 140°C, the device brings the outputs up through a typical soft-start.
