This section includes a list of supplies required to perform tests on this EVM.
- Power Supplies: Power Supply #1 (PS #1): A
power supply capable of supplying up 36V at 3.3A is required.
- 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.
- 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.
- Meters: 4x "Fluke 75" multi-meters, (equivalent or better).
- 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.
- USB Communication Kit:EV2400 or EV2500
USB-based PC interface board.
- Software: BQSTUDIO software with latest
.bqz file for the correct BQ2569X IC provided by
Texas Instruments. Download and install BQSTUDIO
