MSP-EXP432E401Y: PMIC Programming device

Part Number: MSP-EXP432E401Y
Other Parts Discussed in Thread: TPS6594-Q1, TPS62875-Q1, , TPS650330-Q1, ASH, DS90UB953-Q1

Hi,

We are planning to use the TPS6594-Q1 and TPS62875-Q1 PMICs to supply a Xilinx FPGA (ZU15EG). We know that we can program the TPS6594-Q1 using the MSP-EXP432E401Y.

My question here is if we can program the TPS62875-Q1 PMIC with the MSP-EXP432E401Y. board (and using the same I2C bus) or if we need another board to do the programming.

Additionally we have a TPS650330-Q1 to supply an image sensor that needs to be programmed too. Can we use again the MSP-EXP432E401Y board to program that PMIC?

Thank you in advance.

Regards,

Jorge Cruz

    You are correct, but please be aware if you're not using the booster board for the TPS6594, you need to populate the pullups. I've seen customers try to do this without using them leaving them confused as to why they're not working.

    Not part of this product line, but I'll redirect after this post, typically the TPS6594 ash an I2C base address of 0x48 for your reference & 0x4C if it's a dual solution.

    Unfortunately not, they are locked from production for compliance of safety standards.

    Hi Jorge,

    Please find the response for TPS62875-Q1 for following question.

    My question here is if we can program the TPS62875-Q1 PMIC with the MSP-EXP432E401Y. board (and using the same I2C bus) or if we need another board to do the programming? 

    • Yes, TPS62875-Q1 need I2C bus to set the configuration. You can set I2C address through MSP board. Let me know if you need help to select the address. 

    Best regards,

    This confused me, because I know that the registers inside the TPS650330-Q1 has to be changed to make a correct power-on sequence, which is needed in my case. Can we use a microcontroller via I2C to change those register or maybe using the DS90UB953-Q1 to do that?

    Thank you for your response

    The device can have it's registers changed, but the static memory that is loaded up into the device's registers can not be over written.

    So the device is powered up, static memory is loaded into registers, I2C writes happen, and the the device is configured to your specifications.

    So in short, yes a microcontroller can change the registers for your correct power sequence.
