4.2.3.2 Software Setup with BQ25713EVM

To setup the software configuration, follow the instructions below:

  1. Open the Application Customization Tool and select one of the following TPS25751D + BQ configurations below.
    GUID-20231109-SS0I-4NWF-LWH6-JJVCB3HJR4ZD-low.svg
  2. Fill out the questionnaire from Q2 to Q10, refer to Section 3.3.3 for more details on each question configuration. All the questions must be filled out to flash or export settings.
  3. Questions 11 through 18 are for Battery Charger (BQ) Configurations.
  4. For Question 11, select BQ25713.
  5. For Question 12, select the INDPM configuration for the BQ25713.
    1. For example, if the user selects "5% - INDPM is set to 5% above the negotiated PD Contract Current" and TPS25751 negotiates a PD contract at 3A, the INDPM is set to 3.15A.
    2. This questionnaire configures register 0x0F - IIN_HOST of BQ25713.
  6. For Question 13, select the VINDPM configuration for the BQ25713.
    1. For example, if the user selects "5% - VINDPM is set to 5% below the negotiated PD Contract Voltage" and TPS25751 negotiates a PD contract at 5V, the VINDPM is set to 4.75V.
    2. This questionnaire configures register 0x0B/0x0A - input voltage of BQ25713.
  7. For question 14, enter the Charge Voltage in units of Voltage (1.024V through 19.2V, 8mV/bit).
    1. This questionnaire configures register 0x05/0x04 - Max Charge Voltage of BQ25713.
  8. For question 15, enter the Charge Current in units of Ampere (0.05A through 5A, 10mA/bit)
    1. This questionnaire configures register 0x03/0x02 - Charge Current of BQ25713.
  9. For question 16 and 17, BQ25713 does not have registers to configure the Charge Termination Current and Precharge Current. These fields are grayed out and do not accept any inputs.
  10. For question 18, enter the Dead Battery Clear Threshold in units of Voltage (2.88V through 19.2V, 64mV/bit)
    1. This questionnaire configures register 0x27 - Global System Configuration of TPS25751 and set "Enable Dead Battery Clear [111]" to '1'.
    2. Upon boot-up from dead battery mode (TPS25751 receives power from VBUS first instead of VIN_3V3), TPS25751 reads register 0x2C - VBAT of BQ25713.
    3. If VBAT voltage is greater or higher than set threshold in Q18, then TPS25751 automatically clear the dead battery flag, otherwise the dead battery flag remains. Refer to the TPS25751 Technical Reference Manual for details.
  11. Refer to Section 3.3.6 for flashing the configuration or exporting the binary.
