JP1 /INT pull-up.
JP2 SCL pull-up rail. not required if using EV2400.
JP3 SDA pull-up rail. not required if using EV2400.
JP4 I/O Pullup rail selection. Selection has either BAT or SYS as the pullup rail.
JP5 D-_ILIM to 2.2 kohm resistor.
JP6 Micro B USB input D- connection to charger D- pin.
JP7 PG pin LED indicator connection. On PG enabled chargers, this indicates the Power Good status.
JP8 STAT pin LED indicator connection. This indicates the current charger status.
JP9 Micro B USB input D+ connection to charger D+ pin.
JP10 USB2ANY pull-up rail. Not required if using EV2400.
JP11 TS resistor divider pull-up rail.
JP12 Charger D+ pin and charger D- pin short connection. Connect this on D+/D- detection enabled
chargers to simulate the connection of a DCP-type USB port as defined by USB BC1.2 and set
IINDPM register to highest setting.
JP13 Connect 10 kohm in parallel with TS resistor network to simulate a battery at 25 C. Disconnect if
using external thermistor.
JP14 CE pin connection to ground to enable charging. When removed, CE pin pulls up to disable charge.
JP15 D-_ILIM to 3.32 kohm resistor.
JP16 D-_ILIM to ground.
S1 QON control switch. Press either for exiting Shipping Mode or System Reset.

Table 2-1. EVM I/O Connections
Jack
J1(2) - VIN Positive rail of the charger input voltage
J1(1) - GND Ground
J2(1) - SYS Positive rail of the charger system output voltage,
typically connected to the system load
J2(2) - GND Ground
J3(1) - VPMID Positive rail of the charger output voltage for power
bank applications in reverse boost mode (OTG).
This output also shares the rail with the VIN input
rail in forward buck mode
J3(2)-GND Ground
J4(1) - BAT+ Positive rail of the charger battery input, connected
to the positive terminal of the external battery
J4(2) - Connection available for external thermistor if
required
TS
J4(3) - GND Ground
J5 Input source Micro B USB port
