TPS6594-Q1: Disabling ALL the BUCKs and LDOs Until I program the device NVM

Nimrod Tenne

Part Number: TPS6594-Q1

Hello,

I need to program the NVM to a different output then the defaults in the manufacturing stage using an external I2C programmer.

the power settings in all 3 of the part numbers listed in the datasheet will damage me design until I reprogram the NVM

1. How can I disable the device power outputs until I program the NVM to my power settings?

2. Is there a part number with only the I2C working - so I can program the NVM - but without any power outputs active?

Thanks

1. If EN is low, the device should stay in a standby/sleep state and the device power outputs should be low.

2. There isn't a part number with only the I2C working. All versions of the devices have at least a default power-up sequence.
