BQ76942: Programming BQ76942

Hi Steven,

If you are referring to OTP, then the answer is not a simple yes or no.  Depending on the device spin you have and if the default OTP settings meet your needs, you may or may not need to rewrite OTP settings.  Additionally, OTP ensures that the default settings that are loaded in upon power up are to your liking.  You can always load in whatever settings you would like each time the device powers up instead of programming OTP.

Please see this FAQ for more information: (+) [FAQ] BQ76952: Common questions for OTP programming with the Bq769x2 Device Family - Power management forum - Power management - TI E2E support forums.

Hi Steven,

You should use the EV2400 for communication between a custom board with the BQ76952 and BQStudio. 

If you have a BQ76952 EVM, then you can connect the EVM to BQStudio using the micro USB port on the EVM.  A simply micro USB to USB cord should work in this scenario.

Here are links to the BQ76952EVM  and EV2400 pages:
