LM10524: 5V as VIN_IO for SPI Interface

Mahesh Gunnam73

Part Number: LM10524

Hi,

Can I Just supply All VIN and VIN_IO pins with 5V for LM10524? Because I am using 5V PIC to control the SPI interface. I don't want that to spoil the PMIC.

Datasheet is quiet not clear in showing this detail.

Thanks,

Hello Mahesh,

The VINxx pins support up to 5.5V max, and the VIN_IO can be as high as VIN. So I don't see any issue to provide 5V to all the input pins. And the SPI pins can support up to VIN, so this is ok as well.

Regards,
Karl
