BQ4050: About ASCCL, ASCDL, AOLDL and OCD

Hello Dongoh,

Thank you,

Hello. check this question, too.

Hi Dongoh,

Dongoh Kang said:

1. ASCCL, ASCDL means FET latch operation.

    normally, recovering the latch needs IC reset.

    but in TRM (14.9.10-11) latch can recover by the time delay.

    I want to design to recover FET automatically by the time delay,

    then how to set ASCCL and ASCDL in Protection B setting (TRM 14.2.4.3) ?

Only the DA Configuration [NR] bit needs to be set to 1 to have the latch reset based on the time delay.

2. what is different from AOLDL and OCD?

   only for latch operation?

OCD is a firmware protection, where this will be typically will be triggered more slowly since it does not rely on the hardware protection mechanism.

Anthony
