输入电压15.5V,IIC没有接的情况下VSYS输出9V。
VSYS端带载电流500mA左右,芯片发热比较严重,没有接铅酸电池充电的情况下,只是在VSYS端接了负载,附件是图纸。帮忙看看图纸有没有问题。

您好,请参考下面的内容
As this is a charge controller, the thermal dissipation/heat will be localized on the external power stage, i.e your external switching FETs and inductor. The key top optimizing thermal performance is making sure you have enough vias to ground plane for effective heat dissipation, and clean uninterrupted ground plane. With regards to choice of external components, you want to minimize
