BQ24715: The charging current of BQ24715 is locked

Part Number: BQ24715

Tool/software:

Hi Ti Team,

We're encountering an issue with the BQ24715 on our new PC project. Due to the project's unique requirements, we need to dynamically adjust the charging current during operation. We initially set the charging current to 4A and successfully stepped it down to 500mA without any problems. However, when we tried to increase the current from 500mA to 1.5A, the charge current got locked at 1A. From this point on, the input current remained unchanged regardless of how we adjusted the charging current setting. Has anyone else experienced this issue?

The read register data:

ChargeOption:9156
InputCurrent:B80
ChargeVoltage:2220
ChargeCurrent:F80

The written register data:

argeOption:9146
InputCurrent:BB8
ChargeVoltage:222E
ChargeCurrent:FA0
