1. DIR, PWM = high
2. The use of X7R material is recommended
3. For higher values, stability at zero load is not guaranteed
4. Tested during qualification only
5. Value depends on T
6. Tested during characterization only
7. Supplied by charge pump
8. See section
9. Voltage between source-drain of external switching transistors in active case
10. The short-circuit message will never be generated for switch-on time < t
