Other Parts Discussed in Thread: BQ25570
Dear Customer Support Center
Now, I am designing a device which is consisted of a solar cell, a secondary battery and a power management IC.
The solar cell generates an electric power energy which is storaged at the secondary battery.
The power management IC feeds the electric power energy from the secondary battery to a load by constant voltage.
From this design concept as above, I've selected BQ25570 EVM.
I would like to ask three questions about each terminal of BQ25570 EVM.
Q1. Are there any problems if a secondary battery connects to the VSTORE terminal?
In fact, I've connected a secondary battery to the VBAT terminal.
Q2. Does the VBAT_OK terminal affect anything inside BQ25570 if J13 terminal connects nothing?
Q3. Is the connection from the following JP1 to JP6 correct when using BQ25570 EVM under the design concept as above?
JP1: NC JP2: GND JP3: VSTORE JP4: 80% JP5: GND JP6: NC
Please don't hesitate to ask if you have any questions.
