3. Specifications at -40° and 105°C are guaranteed by 25°C test with margin limits.
4. Guaranteed by design, not 100% tested in production.
5. This is the maximum duty cycle achievable using the specified values of RTD and CT. Larger or smaller maximum duty cycles may be obtained
6. Adjust VDD below the UVLO stop threshold prior to setting at 7V.
