BQ25898D input current limit setting with ILIM

James Lee

Other Parts Discussed in Thread: BQ25898D, BQ25895M

Team,

In BQ25898D datasheet, it is saying the input current limit will be 1.5A with 260Ohm resistor (KILIM = 350 max).

But with KILIM of 350 and 260Ohm resistor, it would be:

IINMAX = KILIM / RILIM = 350 / 260 = 1.346A

Could you clarify this?

Why we are saying it's 1.5A while in the math above it is 1.346A.

Thanks.

The datasheet is using the maximum KILIM=390 Aohm max to report the maximum ILIM = KILIM / RILIM = 390 A ohm/260ohm = 1.5A.

Does it mean BQ25898D specification is revised recently?

- if yes, please let me know where I can get the latest datasheet

In my BQ25898D datasheet (from March 2016), the maximum KILIM is 350Aohm (min:290, typ:320).

And, does BQ25895M have same KILIM value as BQ25898D(max 390 Aohm)?
