Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

4. DRV1 and DRV2 pulsating at half this frequency, that is, 65 kHz.

5. Not tested. Guaranteed by design and characterization.

6. For coldest temperature, QA sampling at −40

°C in production and −55°C specification is Guaranteed by Characterization.
