DRV8308: CLK50 and TBLANK Tolerance

Jim Gavin

Part Number: DRV8308
Other Parts Discussed in Thread: DRV8307

Hello,

The DRV8308 and DRV8307 datasheets do not specify any tolerance for the CLK50 and TBLANK specifications; only the typical values are specified. I presume that the TBLANK time is based off of the CLK50 internal oascillator, so I can determine the TBLANK tolerance based on the CLK50 tolerance.

Is there any information available on the tolerance or range of CLK50 or TBLANK?

Thank you,

Jim

Hi Jim,

The CLK50 frequency can vary +/- 10% across voltage and temperature.

We could not find any information about TBLANK tolerance. You can assume a +/-10% variation there also.
