2.6 Equipment Setup

BQ25758EVM, BQ25758AEVM

Use the following guidelines to set up the equipment:

  1. Set power supply #1 for 20 VDC, 8A current limit and then turn off the supply.
  2. Connect the output of power supply #1 in series with a current meter to J1 (VIN and PGND).
  3. Connect a voltage meter across J1 (VIN) and J1 (PGND).
  4. Connect load #1 in series with a current meter to J3 (VOUT and PGND).
  5. Connect a voltage meter across J3 (VOUT and PGND).
  6. Set electronic load to CC mode at 4A. Turn off load #1.
  7. Make sure the jumpers are installed as indicated in IO and Jumper Descriptions.
  8. If using Battery Management Studio, use the following steps:
    1. Connect J5 to the EV2400. Connect J5 to the I2C PORT 2 on the EV2400
    2. Turn on the computer and load 2. Open the bqStudio software.
    3. Select Charger and click the Next button.

  10. In 16 Bit Registers, VOUT_REG default is 5000mV
  11. If using TI Charger GUI, use the following steps:
    1. Connect J4 to the USB2ANY. Turn on the computer and load 2.
    2. Navigate to the TI Charger GUI website and select the charger you are using:
      BQ25758EVM, BQ25758AEVM
    3. You should see at the top-left, Hardware Connected. After you see the hardware is connected, select the plug icon on the left panel.
      BQ25758EVM, BQ25758AEVM
    4. This is the Charger Configuration window. Click the Read All Register button at the top, then set WATCHDOG to disabled and set the Output_Voltage_Limit to 5000mV

  12. Buck Test: Set VOUT_REG to 5V (5000mV) and then turn on load #1, measure

    V(J1(VAC)) = 20V ± 0.5V

    I(J1(IAC)) = 1A ± 0.5A

    V(J3(VOUT)) = 5V ± 0.5V

    I(J3(IOUT)) = 4A ± 0.5A

  13. Buck-Boost Test: Set VOUT_REG to 20V (20000mV), measure

    V(J1(VAC)) = 20V ± 0.5V

    I(J1(IAC)) = 4A ± 0.5A

    V(J3(VOUT)) = 20V ± 0.5V

    I(J3(IOUT)) = 4A ± 0.5A

  14. Boost Test: Set VOUT_REG to 36V (360000mV), measure

    V(J1(VAC)) = 20V ± 0.5V

    I(J1(IAC)) = 7.2A ± 0.5A

    V(J3(VOUT)) = 38V ± 0.5V

    I(J3(IOUT)) = 4A ± 0.5A
