Notes
1.
2. Corresponds to an averaged variation of 7 mV/ C.
3. Including the V
4. Extended voltages are allowed if series resistors are used (see Fig.1).
5. The gain between the pre-driver output current and the IDRIVE current is typically; lower source = 35,
6. Typical value for external FET such as PHN210.
7. I
8. I
9. Valid if the STOSC capacitance is in the nominal range of 150 to 700 pF.
