Hi Tiers.
BQ24032A's charging current setting is caculated by below equation.
RSET = V(SET) x K(SET) / IO(BAT)
I want to set charging current 116mA, So
9159 Ohm = 2.5V x 425 / 0.116 and I using 9.1K Ohm(1%).
But Charging Current is 130mA in my board.
Why not 116mA?
I checked EVM, charging current is 116mA in same setting.
I tested swap.
A : BQ24032A in EVM
B : BQ24032A in my board
A is inserted in my board, charging current is 116mA.
B is inseted in EVM, charging current is 130mA.
In same setting, A's charging current is 116mA and B's charging current is 130mA
Why difference between A and B? Is it in tolerance?
Max K(SET) = 450
Max V(SET) = 2.525
Max charging current in datasheet is 450 x 2.525 / 9100 = 124.86 mA
124.86mA is under 130mA.
Please let me know why 130mA ASAP.
Thanks.
