4.1 Hardware Requirements

Figure 4-1 identifies different items on the TIDA-010268 board. Descriptions of these parts are provided in the following list:

  • Connector J2 and J3: This connector is designed to connect with the MSPM0 LaunchPad™ Development Kit. A direct connection can be made with the MSPM0 LaunchPad or a separate control (such as connecting I2C to EV2400 and use the BQ studio for control).
  • Connector J4: Shorting J4 can make the 3.3-V output by BQ7690x provide to the 3.3 V pin of J2.
  • Connector J5: CAN interface, to use this enable 5-V Buck.
  • Connector J6: Shorting J6 can make the 3.3-V output of the TLV704 provide current to the 3.3 V J2 pin. (If using TLV704, enable TPSM365R6V5RDNR first.)
  • Connector J7: Shorting J6 can make the 5-V output of TPSM365R6V5RDNR provide current to the 5-V pin of J2. (If using TPSM365R6V5RDNR, set J2:BUCK EN pin to high.)
  • Connector J8: Battery cell connector, connect cell7 to cell1 from left to right. If using less than 7 cells, short the corresponding pins according to the BQ76907 2-Series to 7-Series High Accuracy Battery Monitor and Protector for Li-Ion,Li-Polymer, LiFePO4 (LFP), and LTO Battery Packs data sheet.
