DRV8850: What to do with LDOFB input if LDO is disabled?

Scott Brenneman

Part Number: DRV8850

We're not going to use the LDO in the DRV8850, so we'll leave the LDOEN pin open and let its internal pull-down disable the LDO. Given that the LDOFB pin is an input, what should we do with it in this case? Leave it open?

Thanks,

Scott

Hello Scott,

Yes you can leave the LDFB pin open, the LDO will be disabled by the internal pull down resistor. Thank you.
