I have a question to ask，During the process of charging the battery with BQ25703a, if the battery is suddenly unplugged, the VBAT voltage of BQ25703a will experience an overshoot, as shown in Figure 1. How can…
Hi Tiger
zhong susan said: Then I tried to add an RC filter circuit to the SW pin as shown in Figure 2 to reduce this overshoot, but I found that the overshoot became more severe after adding the RC filter circuit. I don't understand why
Is this situation…
