Part Number: BQ76952

I'm planning to use BQ7695202, but for now I'm checking using BQ76952(EVM).

For the firmwear of host, is the difference between two devices only in what is written on Device Comparison Table?

"REG1 LDO Default" is set to "Enabled, set to 3.3V".
Does this mean that the Data Memory Settings are as below?

・Settings:Configuration:REG12 Config
　REG1V_2–REG1V_0 = 6(3.3V)
　REG1_EN = 1(REG1 Enabled)

・Settings:Configuration:REG0 Config
　REG0_EN = 1(Preregulator is disabled)

Hello Takayama-san,

Correct, that is the only difference between both devices. Only the CRC and REG settings would be changed.

Hello Takayama-san,

For new questions, please post a new E2E thread. Posting on solved threads makes it more difficult for us to track and also makes it more difficult for others to find relevant threads.

To answer your question, you can use the EVM with the BQ7695202 with no problem. You can also configure an EVM part to have the same settings to the BQ7690502.

Best Regards,
