Part Number: TPS23880

Hi,

Our customer now is planing to use 3 of TPS23880 for 12 port PSE.

Is there any source code of MSP430 about multi-PSE application?

If no, then any suggestion for this application on SW?

Thank you.

C.T.

    Hi C.T,

    As our EVM only has one TPS23880 device, the MSP430 reference is designed for single TPS23880 control. However, it s expandable to multiple PSE devices. The MSP430 reference is a good reference to start. If customer wants to understand how to do port power management, we also have that reference on ti.com and the EVM user's guide has detailed explanations. For SRAM code loading and general PSE configurations(if all ports have same configurations), you can use broadcast address(0x7F) to program all the devices at the same time. For port control and status read, you will need to access to each device separately. Thanks.

    Best regards,
    Penny
