DW06D Battery Protection IC burning LDO
Posted: Fri Feb 05, 2021 8:43 pmHi all,
I badly need your help.
I have a PIR sensor setup. It works fine without the DW06D LiPo battery protection IC.
Yesterday I added the battery protection IC (instead of just bypassing it) since the DW06D took some time to ship. This is U1 in my schematic.
The moment I inserted the 18650 battery, the LDO started emitting smoke and burnt.
I then made a small board to test the DW06D, everything worked as expected and combined with the same LDO, MCP1700, it was outputting 3.3V.
I thought that I probably shorted something when I soldered it onto my PIR board. So I soldered it again, and inserted the battery, everything went fine. I just had to clean up some solder point, so I removed the battery, and reinserted it a few minutes later, and AGAIN the MCP1700 burnt!
I don't understand what is going on. Why is the DW06D in place burning my MCP1700 on my board! Please help!
