Table 2-4 Jumper Description
JumperDescriptionFactory Default
JP1Use JP1 to connect the default feedback resistor and set the charger to the default 7 cell battery.Installed
JP2Use JP2 to connect a new feedback resistor to program a different cell count.Not installed
JP3Use JP3 to connect external IOUT resistor. JP3 can be shorted to PGND to turn off hardware output current limiting.Not installed
JP4Shunt JP4 to use default IOUT resistor. By closing JP4, the default IOUT current is set to 10 A.Installed
JP5Shunt JP5 to bias TS.Installed
JP6With JP5 shunted (REGN connected for voltage divider). Shunt JP6 to set TS status to normal.Installed
JP7With JP5 shunted (REGN connected for voltage divider). Use JP7 to connect external resistor to change TS status.Not installed
JP8Use JP8 to connect external FSW_SYNC resistor.Not installed
JP9Shunt JP9 to use default FSW_SYNC resistor. By closing JP9, the default switching frequency is set to 250 kHz.Installed
JP10Shunt JP10 to use default IIN resistor. By closing JP10, the maximum input current is set to 8 A.Installed
JP11Use JP11 to connect external IIN resistor. JP11 can be shorted to PGND to turn off hardware input current limiting.Not installed
JP12Use JP12 to select the gate driver source. Shunt pin1 to pin2 to use IC internal LDO REGN output. Shunt pin2 to pin3 to use external gate drive supply. Maximum external gate drive supply can be up to 11 V.Pin1 and pin2 shunted
JP13Shunt JP13 to enable controller in forward mode. Open JP13 to disable controller. The /CE pin can also be used as a general purpose indicator.Installed
JP14Shunt JP14 to connect /INT to a pullup rail.Installed
JP15Shunt JP15 to connect STAT1 to a pullup rail. The STAT1 pin can also be used as a general purpose indicator.Installed
JP16Shunt JP16 to generate on board 3.3-V pullup rail.Installed
