TPS6594-Q1: how to do the NVM programming of the TPS65941

Ted Zhang

Part Number: TPS6594-Q1

HI Team,

My customer request the GPIO3 to output high by default after the VCCA is attached, is this doable by program the NVM register GPIO3_CONF and GPIO3_OUT? I didn't find the NVM program steps in the datasheet, can customer directly use the I2C on their own board and program the PMIC NVM? Do we have any program steps, I suppose there must be some special sequence to unlock the NVM and be able to program the device.

Thanks.

Hello,

At this time we are not currently supporting reprogramming of the TPS6594-Q1 family of devices. We can work with you and your customer to provide custom NVM configurations. Please reach out to the business unit for a quote and schedule.

Thanks and Regards,

Chris

HI Chris,

Thanks for your feedback. Since the NVM is base on the EEPROM, it should support the multiple time NVM programing. Can you share any reason behind it? For my customer's case, if we can't help to reprogram the EEPROM then they'll need to re-build the PCB board...

Hello Ted,

We followed up with you on this matter via conference call earlier this week. While we are still not currently supporting reprogramming of the devices, was the information provided enough to resolve your customer issue?

Regards,

Mike
