Hi,

Could you tell me about Ilim.
Customer want to the current limit to 4A.
However, the data sheet is the following description exists.
If PSEL is in a state of Low, Ilim value does it become a 3.25A?
Could you tell me how to set to 4A.

Maximum input current limit setting is 3.25A, either using the ILIM resistor or I2C register.

Jeff-san,

Thank you for your support.
Let me ask you one more thing.
Does bq25892 give priority to either of PSEL pin and Ilim pin?

For example,
・PSEL=High(500mA) vs Ilim=(1A)
・PSEL=Low(3.25A) vs Ilim=(1A)
How does current limit level of this condition?
Could you give me your advice?

The ILIM resistor sets the maximum input current limit per PSEL pin.
