Other Parts Discussed in Thread: EV2400, BQ76920
Our equipment is EV2400 + BQ76920EVM + Power Supply(attached picture)
We follow SLVU924D bq76920 Evaluation Module User's Guide 2.2.1 AFE Quick start,
8.onnect a 0-V DC power supply capable of 250 mA minimum to the “BATT” terminals and adjust to
approximately 18 V.
10. Start the bq769X0 evaluation software. The GUI should display. Click on the Scan box to enable
repeated update of the display. The power supply may be adjusted within range of the part to observe
voltage changes in the GUI display Stack V/T/I section.
Please refer to the attached picture.
The Battery Voltage should be 18, not 16.370
The Voltage Cell 1 should be 3.6, not 0.05
The Voltage Cell 2 should be 3.6, not 4.392
The Voltage Cell 3 should be 3.6, not 3.991
The Voltage Cell 4 should be 3.6, not 3.994
The Voltage Cell 5 should be 3.6, not 3.991
Even though we shutdown the system, then boot it again, this fail situation is still the same.
Could you please help us to check what is wrong?
Does it mean the hardware component (near Voltage Cell 1)should be replaced or something?
