Hi Dexter,

The tolerance of the pull down resistor for /CE pin isn't something that is specified due to how the /CE pin is connected in most designs.
Is there a certain design application that requires you to know the tolerance?

Dear Anthony,

We need to calculate current consumption Min/Max because our system is sensitive power consumption of BATTERY.

My application is TWS cradle. When normal operation is used Pull up at CE pin from BATTERY POWER.

please let me know the tolerance of internal pull down resistor in CE pin.

Thanks.
