We are having some problems with the charge current limit for the MP2632. We have designed it for 2A charging current but we are only getting 900mA charging current as measured by the volt drop across the sense resistor of 10 mOhms. Riset is 75K and we have a 200 Ohm resistor between DM1 & DP1 so believe the charger is using the charge current limit as set by Riset. Iilim resistor is 14.7K so should be set to 2.7A input limit.
We have tested the battery pack on a PSU and it wants to take 2A in constant current mode. We have looked at the voltage sensing lines from Rsense and do not see any appreciable noise on this signal.
The layout is not identical to the eval board but is close, could a lay out issue case this problem. Any guidance would be appreciated.
