TAS2770: Getting started with IV sense and speaker protection on a Host CPU

M.A.M
Expert 8835 points
Part Number: TAS2770


Hi,

My customer is looking at implementing the Speaker Protection Algorithm on their host , but I do not see much useful info on the web page that provide the guidance needed here. Please help me out.
I assume that the steps should be something like

1- Get an EVM and connect the customer speakers
2- Run PPC3 and characterize the speaker thermal properties
3- Save coefficients in a golden startup I2C config file for the TAS2770
4- Get access to TI source code for the Speaker Protection algorithm, and build into the host software

However, I did not find much other than a link to the TAS2770 Linux driver in the GIT tree...

Please return to me with a full check list of the steps that we need to follow, and where to find the SW resources of the algorithm. Via my TI email is also OK.
Thanks and best regards, M.A.M

    Hi M. A. M.

    Can you please reach out directly through private e2e message or to my email? ivan.salazar@ti.com

    In order to port our algorithm into customer processing platform we will require several details of the platform, and our software team has to check if the platform is compatible. In addition our team is working on the porting as we're not releasing any proprietary data related to our speaker protection algorithm.
