4.3.1 Hardware Setup with BQ25756(E)EVM

To use the TPS25751AEVM and BQ25756EVM, the following items are needed:

  1. TPS25751AEVM
  2. Ribbon cable (included with TPS25751AEVM)
  3. BQ25756 interposer board (included with TPS25751AEVM)
  4. Application customization tool
  5. BQ25756EVM
  6. BQ25756EVM user's guide and datasheet
  7. BQStudio with EV2400 (optional)
  8. DC power supply or battery simulator

To setup the hardware, follow the instructions below:

  1. Connect the J11 and J13 mating connectors of the TPS25751AEVM to the reciprocal connectors on the provided BQ25756 interposer board. The silk-screen BQ25756 on the BQ25756 interposer board must be oriented on the same plane as the top of the TPS26750EVM. See TPS25751AEVM and BQ25756(E)EVM Hardware Setup.
  2. Unscrew the screws on headers J1 and J3 of the BQ25756EVM enough for the BQ25756 interposer board prongs to fit into the aforementioned headers.
  3. Insert the other side of the BQ25756 interposer board to headers J1 and J3 on the BQ25756EVM. Verify the prongs are inserted all the way into the headers.
    Note: Repeated insertion and removal of TPS25751AEVM mating connectors from the BQ25756 interposer board (depending upon how the boards are grasped and pulled) can cause the prongs on the side of the interposer board connected to the BQ25756EVM to come out of the J1 and J3 headers enough to cause an insufficient electrical connection between the BQ25756EVM and the TPS25751AEVM. Please recheck interposer board connections when detaching and re-attaching BQ25756EVM from the TPS25751AEVM.
  4. Tighten the screws on headers J1 and J3 of the BQ25756EVM.
  5. Attach the ribbon cable to header J12 on the TPS25751AEVM as shown in Figure 4-2.
  6. Connect the other end of the ribbon cable to J8 header of the BQ25756(E)EVM.
  7. To power the board using a simulated battery, connect the simulated battery to header J3 in the orientation shown on the silkscreen (+ and - symbols next to J3).
  8. For setting the proper jumper for battery charging application, refer to BQ25756 Evaluation Module User's Guide. Incorrect jumper settings or insufficient input power can result in a faulty evaluation.
