BQ24266: Changing charging current between two values

Part Number: BQ24266

Hello all,

I'm interested in changing the charging current between two values: 1.5 and 2.5A.

The change in current is will be done by using a single I/O (Logic Low = 1.5A, Logic High = 2.5A)

What is the best way to change the value of the ISET resistor in order to achieve that?

Can I simply connect in parallel resistor to Rset and use a FET in order to "create" a new resistor value?

Is there a preferable way to accomplish this?

Thanks!
