2.1 Input/Output Connectors
Table 2- 1 lists the input/output connectors
Table 2-1. Input/Output Connectors
Setup Connection Description
J 1 -USB USB charger input/output header can be used as either an input or an output.
If R6 is opened, then J
1 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, J
1 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 J 1 .
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 TPS650 1 0
J8-Interface header Header that duplicates the signals from J5 interface connector
J9-VBAT-VINMAIN VBAT output and VINMAIN and VINCORE inputs of the TPS650 1 0 are connected
to this header. Short these two pins together to run the TPS650 1 0 main and core
converters from the battery. To easily evaluate the performance of the TPS650 1 0
when running from different battery voltages, remove the jumper and connect an
auxiliary supply to the VINMAIN pin.
J 1 0-GND Return connection for auxiliary VINMAIN supply
J 11 -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
1 0-k Ω
battery thermistor.
J 1 2-VCORE Output voltage of the core converter
J 1 3- GND Return connection for core converter
J 1 4-VMAIN Output voltage of main converter
J 1 5-GND Return connection for main converter
J 1 6-Input/Output BIT Header that contains the /MPU_RST, /RESPWRON, /PWRFAIL, /INT, and
LOW_PWR inputs and outputs of the EVM
