Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- the Recommended Operating Ranges limits may affect device reliability.
- Currents are defined as positive into the device and negative out of the device.) Symbol UnitMaxTypMinCharacteristicParameter OUTPUTS [ALL EXCEPT FOR FAN3225(C/T)MX−F085] tRISE Output Rise Time (Note 12) CLOAD = 2200 pF 12 20 ns tFALL Outp.
- MillerDrive Output Architecture** DD supply voltages have noise from the power switching.
- To give a numerical example, assume for a 12 V V DD (VBIAS) system, the synchronous rectifier switches of Figure 56 have a total gate charge of 60 nC at V GS = 7 V .
- To ensure reliable operation, the maximum junction temperature of the device must be prevented from exceeding the maximum rating of 150°C; with 80% derating, T J would be limited to 120 °C.

Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
