Hi Frank,

have you had a look at this TI's "Current/voltage/power monitors" website?

Hi Kai,

I survey the web before using e2e, but only find the lm5056a which is too large here. They need small size or as the competitor. Thanks.

Hello Frank,

You can use the BOM Cross Reference Tool. Here you can quickly see the device options and how similar they are. From me running the Tool the INA230 seems like a good alternative although the pinout and the specifications are not the same.
