TPS38700: GUI software, programming and turn-off delays.

Part Number: TPS38700

Hello,

A few questions regarding the TPS38700:

I would like to evaluate the TPS38700 GUI, but the link leads to the FUSION POWER DESIGNER which doesn't have the TPS38700 in the list of available devices. How can I access the TPS38700 GUI?
Can our specific power up/down sequence be programmed into the non-volatile memory through the I2C interface?

Thank you in advance,

Alex

Hi Alex,

Thank you for your question, please refer to the EVM user manual for the quick start up on section 4.2

Yes, the timing sequence can be programmed through the I2C. Unfortunately this device does not have a NVM and will require programing when powering on.

Hi Jesse,

The datasheet mentions several times an OTP memory which holds a default configuration.

So just to verify, I don't have a way to configure this OTP and change the default configuration, correct?

Can you recommend another 12CH sequencer that has a programmable NVM and flexible control over the power on and off sequences?

Thanks again,

Alex

Hi Alex,

If you have a definition that you would want as a default stored in the OTP we can do that for you during manufacturing. This device can be fully customized to your needs as a deliverable.

If that is something that you are interested in I can get you in contact with one of our systems engineer to discuss this option.

Hi Jesse,

Yes, that may be something that I'm interested in and I would like to further discuss this option.

Regarding the GUI, it seems that I can't experiment with the TPS37800 offline. I must have the EVM connected to use the GUI, correct?

Thanks again,

Alex

Hi Alex,

Sure I will send you an email with our systems engineer.

Also, yes you will need the TPS38700 connected to the I2C to operate the GUI.
