Part Number: BQ24725A
pls help to review BQ24725A schematic. customer use 2 BQ24725A to charge 2 batteries in one system.
Here are my comments to the design:
1) It looks like this is a pretty bare-bones design with no need for the power path features of the charger, nor the current limiting features as you have tied ACN and ACP together.
From my analysis, the design looks fine, albeit not a typical design for most other customers utilizing this device.
I would also just confirm that you want the lowest input voltage detected to be around 18.3V, as per the ACDET resistor divider.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Joel Hernandez II:
Yes, input voltage detection is 18.3Voltage, Do you feel set too low?
In reply to Tom Chiou:
Not necessarily, I just wanted to confirm that this is what you required for your design. This value will be based on the minimum voltage of your power supply.
And just to confirm, the implementation is simply to charge the battery, correct? You don't require any of the other power path features, correct?
Yes,just to charge the battery, the discharge part is discharged through the diode
Understood. I have no other comments.
