BQ76952: [OTP] Checking the number of signature values already registered in the device

Kyungjae Lee
Intellectual 660 points
Part Number: BQ76952

Tool/software:

Hi,

According to the BQ76952 TRM the device is said to support up to eight different signature values. Is there a way to check the number of signature values already registered in the device due to partial changes in OTP? In other words, is there a way to check how many partial changes in OTP I can do before I run out of the given eight partial changes?

Thank you,

Kyungjae Lee

    Hello Kyungjae,

    The subcommand 0x00A0 OTP_WR_CHECK() can be used to check if OTP writing can still be accomplished or not, however, there is no method to check exactly how many changes are left before you cannot do any more. 

    Best Regards,
