2.3 Equipment

This section includes a list of supplies required to perform tests on this EVM.

  1. Power Supplies: Power Supply #1 (PS #1): A power supply capable of supplying up 36V at 3.3A is required.
  2. Load #1 for simulating a battery: Best option: 4-Quadrant Supply, voltage source/sink capable of up to 34V and ±3.3A (or higher). A 1000uF capacitor connected in parallel is also recommended.

    Alternative Option: Up to 34V, at least 3.3A, DC electronic load set in a constant voltage loading mode. A second power supply connected by a diode in parallel with the electronic load may be needed to apply a startup voltage < simulated battery voltage.

  3. Load #2 for simulating a load at SRN (battery) for BQ25692/92Q1 non-power path in forward/charge/sink mode. Or to connect to VPWR for a load in reverse/OTG/source mode: Electronic or resistive load capable sinking at least 3.3A from up to 36V.
  4. Meters: 4x "Fluke 75" multi-meters, (equivalent or better).

  5. Computer: A Windows 10 or 11 based computer with at least one USB port and a USB cable. Must have the latest version of Battery Management Studio installed.
  6. USB Communication Kit:EV2400 or EV2500 USB-based PC interface board.
  7. Software: BQSTUDIO software with latest .bqz file for the correct BQ2569X IC provided by Texas Instruments. Download and install BQSTUDIO from https://www.ti.com/tool/BQSTUDIO.
