I was trying to replace pack of 3 NiMH batteries with single Li-Ion cell in my battery operated screwdriver. For ovecharge and overdischarge protection I was using small PCB with 4056E, DW01 and 8205A chips. Schematics of the board is attached. The problem is that the PCB blows up whenever I turn the screwdriver on.
Is there a problem in connecting inductive load (a motor) to the board? Could a reverse polarized diode between B- and OUT- do some help?
The motor is taking 1A to 2A depending on load so I think there is no need to replace 8205A (which is rated up to 5A) with stronger MOSFET. Am I right?
