Part Number: BQ24780S
Other Parts Discussed in Thread: TIGER

Dear expert,

When BQ24780S works in boost mode, what's the typical response time or bandwidth during load transient?

Can anything from hardware or software be done to increase the dynamic performance to avoid trigger prochot?

Best regards,

Dylan

Hi, Dylan,

You can set Fast DPM Deglitch Time (FDPM_DEG) in ChargeOption3 register. FDPM_DEG is response time from system current exceeding Fast DPM Threshold to battery discharge in boost mode. The minimum deglitch time is 50us.

Hi Tiger,

If the charger has already worked in turbo boost mode, which register can make the discharge current increased more quickly?

Thanks,

Dylan
