Table 2-4 Jumper Description
JumperDescriptionFactory Default
JP1Use JP1 to connect the default feedback resistor and set the charge voltage to a 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 ICHG resistor. JP3 can be shorted to PGND to disable hardware output current limiting.Not installed
JP4Shunt JP4 to use default ICHG resistor. By closing JP4, the default ICHG current is set to 10A.Installed
JP5Shunt JP5 to bias TS with REGNInstalled
JP6With JP5 shunted, REGN is connected for the TS voltage divider. Shunt JP6 to set the TS status to normal.Installed
JP7Use JP7 to connect external resistor or thermistor to change the TS status. Disconnect JP6 when adding an external resistor.Not installed
JP8Use JP8 to connect an external FSW_SYNC resistor. Disconnect JP9 when using an external FSW_SYNC resistorNot installed
JP9Shunt JP9 to use the default FSW_SYNC resistor. By closing JP9, the default switching frequency is set to 250kHz.Installed
JP10Shunt JP10 to use default ILIM_HIZ resistor. By closing JP10, the maximum input current is set to 8A.Installed
JP11Use JP11 to connect external ILIM_HIZ resistor. JP11 can be shorted to PGND to disable hardware input current limiting.Not installed
JP12Use JP12 to select the gate driver voltage source. Shunt pin1 to pin2 to use the IC internal LDO REGN output. Shunt pin2 to pin3 to use an external gate drive supply. The maximum external gate drive supply can be up to 11V.Pin1 and pin2 shunted
JP13Shunt JP13 to enable the controller in forward mode. Open JP13 to disable the 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 3.3V pullup rail.Installed
