TPS65983B: Stand Alone

Corey Williams

Part Number: TPS65983B
Other Parts Discussed in Thread: TPS65987D, TPS65982

Hello,

Does the TPS65983B come pre-loaded with FW to function as a stand alone device? Our intent is to interface it with a charger and tablet, where the tablet will need to switch from host and device. Will the TPS65983B need FW development to enable role swapping?

Thank you,

Corey

Hi Corey,

The TPS65983B cannot operate as a stand alone device and is only recommended for use in TBT device systems following an intel reference design. I would suggest looking at the TPS65987D as it can operate in stand alone by using a default configuration and is also PD3.0 capable.

Thank you, Eric.

I have purchased the TPS65982 EVM and I am able to act as a DRP with the help of the configuration switches. Does this EVM contain special FW or would all TPS65982 come from the factory with this capability?

Thank you,

Corey

Hi Corey,

The TPS65982EVM contains custom FW to emulate all of the different modes of operation. You would need an external SPI Flash on your board and can create the configuration image using our configuration tool that can be found on the product page.

Thank you, Eric.

Does the TPS65987D come loaded with any FW from the factory? If so, what is its default configuration? Is there a way to enable DRP mode without FW?

Thank you,

Corey

Hi Corey,

Table 7 in the TPS65987D datasheet highlights the various default configurations supported by the TPS65987D.

Here is a link to the datasheet:

Thank you, Eric. Sorry for the back and forth. I have the TPS65982EVM, but I am having trouble charging more than 1.2A. Can you point me to the binary or project file that has the default settings for this EVM?

Thank you,

Corey

Corey,

The default image on the 82EVM cannot be modified. As I mentioned before the 82EVM uses custom firmware to help emulate the various modes the TPS65982 supports. I would suggest you download the TPS6598x Application Customization Tool and adjust some of your settings using the tool. There is a user's guide included with the tool as well.

Here is a link to the tool:

Thank you, Eric.

Is the custom FW loaded into the external SPI flash (U1)?

Hi Corey,

Yes, that's correct.
