Connecting the BQ79600EVM to TMS570 LaunchPad
The following configuration needs to be set correctly on the EVM before connecting to LAUNCHXL2-
TMS57012 LaunchPad™:
•
Ensure that J6 jumper on BQ79600EVM is connected in position 1-2 (default) to connect 3.3-V
supply from the LaunchPad to BQ79600-Q1 VIO pin. TMS5701224 microcontroller does not
support 5-V option, therefore avoid powering VIO pin with 5 V when connecting to the LaunchPad.
•
Remove plastic screw H1 on the left side of the board.
•
If UART communication is used to communicate to the MCU, place R7 and R9 0-
Ω
resistors, and
remove R8 and R10 resistors on BQ79600EVM. The EVMs are populated this way by default.
•
If SPI communication will be used to communicate to host, place R8 and R10 0-
Ω
resistors, and
remove R7 and R9 resistors on BQ79600EVM.
For correct functionality of the LAUNCHXL2-TMS57012 LaunchPad™, ensure JP2, JP3 and JP6 are
placed, and JP1 is removed.
The EVM and the MCU are connected using the female connectors J7 and J9 on the bottom side of the
BQ79600EVM and the male connectors J2, J3, J4, and J5 on the top side of the LAUNCHXL2-TMS57012
LaunchPad™. Connect the J7 20-pin female connector on the bottom side of the BQ79600EVM to the J2
and J3 10-pin male connectors on top side of the LAUNCHXL2-TMS57012 LaunchPad™, and J9 20-pin
female connector on the bottom side of the BQ79600EVM to the J4 and J5 10-pin male connectors on the
top side of the LAUNCHXL2-TMS57012 LaunchPad™, as shown in
. By default, the TMS570
LaunchPad is powered by the USB port on the host computer.

Connecting BQ79600EVM to BQ79616EVM
The EVMs are connected using 4-position Molex connectors. The BQ79600EVM has a high side (J15)and
low side (J14) communication connector available on each board. To connect the BQ79600EVM to the
BQ79616EVM using NORTH direction for communication, connect J15 on the BQ79600EVM to J10 on
the BQ79616EVM. If several BQ79616EVMs are stacked, connect them as indicated in the EVM user's
guide for the BQ79616-Q1 device. If using ring architecture, connect J11 of the top most BQ79616EVM to
J14 on the BQ79600EVM.
