DRV8873: DVDD Maximum current

Olivier Schrevens

Part Number: DRV8873

Dears,

Need to supply few parts with the DVDD internal regulator.

Have seen 2 op-Amp on the dev. board supplied that way for a total of 1.1mA.

What's the maximum current that can be sourced from the DRV8873H DVDD Pin?

Regards,

Hi Olivier,

The DVDD LDO was designed to source up to 2mA external load.

The two op amps shown are used for level shifters. In most applications there is no need for them, as the SR and MODE inputs will be directly set.

Hi Rick,

I have other parts than the two op-amp in mind.

Thanks a lot for your fast and precise answer!

Best regards,

Olivier
