Table 2-1 lists the input/output connectors
Table 2-1. Input/Output Connectors
Setup Connection Description
J1-USB USB charger input/output header can be used as either an input or an output.
If R6 is opened, then J1 can be used as an input. An external 5 V can be supplied
to the EVM to simulate the USB 5-V bus.
If R6 is shorted, J1 may be used as an output. The USB 5-V bus from the PC gets
routed through the EV2300 to J5. Shorting R6 connects the USB 5-V bus to J1.
J2-GND Return connection for USB charger input/output.
J3-AC AC charger input
J4-GND Return connection for AC charger input/output
J5-Interface
connector
Connect one end of supplied Molex cable to this connector. The other end attaches
to USB connector on EV2300.
J6-Vibrator Header that connects optional vibrator to EVM
J7-GPIO Header that contains four GPIO signals that connect directly to TPS65011
J8-Interface header Header that duplicates the signals from J5 interface connector
J9-VBAT-VINMAIN VBAT output and VINMAIN and VINCORE inputs of the TPS65011 are connected
to this header. Short these two pins together to run the TPS65011 main and core
converters from the battery. To easily evaluate the performance of the TPS65011
when running from different battery voltages, remove the jumper and connect an
auxiliary supply to the VINMAIN pin.
J10-GND Return connection for auxiliary VINMAIN supply
J11-Battery Connect a user-supplied Li-Ion battery to this header. If the battery has a
temperature sensor, connect it to the TS pin. See the datasheet for a description of
how to setup the EVM for a battery with a temperature sensor. The EVM default
configuration is for a battery with no temperature sensor. R22 simulates a 10-kΩ
battery thermistor.
J12-VCORE Output voltage of the core converter
J13- GND Return connection for core converter
J14-VMAIN Output voltage of main converter
J15-GND Return connection for main converter
J16-Input/Output BIT Header that contains the /MPU_RST, /RESPWRON, /PWRFAIL, /INT, and
LOW_PWR inputs and outputs of the EVM
