Part Number: BQ3050
Other Parts Discussed in Thread: BQ8050,

Tool/software:

Hi TI engineer:

        Our new batch of products, BQ8050 PWM pin damage probability is very high, up to 5%.  We would like to know what hardware causes are likely to cause damage to BQ8050 PWM pins

Looking forward to your reply! thank you!

    Hi,

    Which pens are you referring to?

    You are using BQ3050?

    Thanks for you reply!

    The following is a detailed explanation

    We have a project that uses 8050 RC6 to do PWM function, the market feedback has a 5% chance of RC6 damage, the pin can not send PWM; We did some tests (such as pulling the pin down or setting it at a very high level) but there was no recurrence of damage;

    We use the BQ8050 chip

    Looking forward to your reply! thank you!

    Hi,

    BQ8050 is a generalized hardware platform we have many devices that utilize the 8050 hardware, can you please be more specific?

    In general, I would say do not violate abs max on any pins, as this will cause damage.

    Regards,
