Hello TI team,

Im going to use the above PMIC IC for my project and im going to set current limit, Phase usage etc as per our customization. Is there any tool available from TI side so that i can set the configuration and generate the OTP file and then flash over I2C line on requirement basis.

Really looking for response and guidance how to proceed here for further configuration.

Hi Bala,

Have you checked https://www.ti.com/lit/ug/snvu596/snvu596.pdf configuration manual? This document describes in details what registers can be written by customer.

Also to note that OTP itself cannot be programmed by customer to make change permanent or non-volatile. Only registers which will stay as long as VANA stays high and/or NRST is toggled.

But really for the actual register writes please see below OTP configuration excel. Once you provide this to us we will in return provide register address = register data formatted file to you.
