Hello, I want to charge 2 series 18650 battery with MP2672. Each battery is removable because of that can be inserted in wrong polarity. Is it okay to add reverse polarity protection with high side switch with p mos after each 18650 and use MP2672. Or can you suggest me anything about removable battery charging?
Hello @yildirimmihsann,
Welcome to MPS forum. Reverse polarity protection can be implemented using schottky diodes with lower forward voltage drop. As you mentioned, adding a PMOS could be beneficial but it is also important to select the MOSFET with low Rdson and low gate threshold voltage.
