本人在TI采购了一块BQ25570EVM-206的demo板，在测试冷启动电压时，发现至少要460mV的输入电压才能开始冷启动。这和datasheet提供的最大冷启动电压400mV相差很大，这是为什么呢？
板子上把VOUT给disable的；VBAT端没有电池，只有个10uF的电容；VSTOR是悬空；VIN通过B2902A作为电源，模拟太阳能。这个有问题么？
您好！条件都是满足的，也用万用表测量了芯片PIN脚附近的电压VIN，和B2902电源输出的一样。只有当VIN≥450mV时，冷启动才会启动起来。
We have found an issue with the cold start circuit. There is PCN pending which increases the VIN(CS) typical to 600mV and maximum to 700mV.

好的，谢谢！
