BQ25606: Peak current of Ichg=2A is not achieved on the part.

Part Number: BQ25606

Hi All,

I am using BQ25606.

Settings on the board are as below

Rilim = 165 Ohms ~ Iilim= 2.89A

Rchg=300 Ohms ~ Ichg = 2.25A

R95 = 6.1k

R99 = 10k

R100 = DNI

RT1 = DNI

I tried to keep the configurations similar (resistors) to the eval board which I have but the charge profile I get on the eval board is different as compared to board which I made.

For the evaluation Board I get the peak current of around 2A, but on the new designed board I get the peak current of only 1.5A

Can I please know what might I be missing here? I tried this multiple times but still shows the same issue. I made sure the Battery discharges every time before testing and shows 0V as well.
