这的确是个问题啊，这个是为了散热吧，不会影响正常的电流sense功能吧，看框图，Rsense已经内部通道连接了，没有看出需要依靠sense-epad之间的路径？难道上电瞬间是热保护了？

SENSE, Exposed Pad: Current Sense Node and Internal
N-channel MOSFET Drain. An internal sense resistor
between IN and SENSE is used to implement the 1.5A
overcurrent threshold. The exposed pad is connected to
SENSE and must be soldered to an electrically isolated
printed circuit board trace to properly transfer the heat
out of the package. To disable the overcurrent function,
connect SENSE and the exposed pad to IN.


【 在 jiu 的大作中提到: 】
: 那sense要接到散热的pad上面去啊。
