BQ25601: IINDPM register set and effect time interval

Will Wang47

Part Number: BQ25601

Hi team,

Customer is using BQ25601 in their project, and they are reaching out to check about the time between IIDPM register set and its effect time. Like the following figure shows, set the IINDPM register at t1 time, and the setting take effect at t2, what's the delta time dt between those two time? Could you help check about this? Thanks.

Thanks and best regards,

Will

Will,

Why do you care about the delta time?

Thanks,

Hi Ning,

Customer design logic need to change the IINDPM register in real time, so they care about the time interval between the command and it take effect, could you comment on the time interval?

Thanks,

Will

Will,

The IINDPM register setting should be changed immediately. The actual loop response time dependents on the external output inductor and output capacitor etc.

Thanks,

Ning.
