JP1
For bq24190/2/2i/3/6 and bq24292i input current setting:
PSEL LOW: Adaptor input
PSEL HIGH: USB input
JP2
D-/PG pin selection
JP3
STAT, PG, /CE, INT, OTG pin internal pull-up source (VSYS) jumper
JP4
USB current limit selection pin during buck mode and PSEL is high (JP1- Not installed
High)/Enable pin during boost mode.
In buck mode: OTG = High, IIN limit = 500 mA;
OTG = Low, IIN limit = 100 mA.
The boost mode is activated when the REG01[5:4] = 10 and OTG pin is
HIGH.
