BQ25713: ACP/ACN related schematics

Part Number: BQ25713

Hi,

Regarding the BQ25713 schematics quoted from EVM user guide as below, what is the effect if we change C46/C47 to 0.01uF and R11/R12 to 10ohm?  Does it matter or not?  THanks!

Thanks!

Antony

    Hi Antony,

    Please refer to the datasheet Section 10.2.2.1 ACP-ACN Input Filter, your design has 100ns time constant and is in the recommended range. It has less delay and high frequency rejection effect than the EVM design, but should be ok with good layout design.
