Abstract:
1. A protection circuit module (PCM) for a secondary battery comprising a bare cell, the PCM comprising: a flexible printed circuit board (FPCB); control circuitry mounted on the FPCB via adhesive material and configured for electrical coupling to the bare cell through the FPCB, the control circuitry being adapted to control charging and discharging of the bare cell, the control circuitry comprising a controller and a switch comprising a first switching device and a second switching device; a plurality of first wire bonding pads on the FPCB around the controller, wherein the controller is electrically coupled to the first wire bonding pads via first wires; and a plurality of second wire bonding pads on the FPCB around the first and second switching devices, wherein the first and second switching devices are electrically coupled to the second wire bonding pads via second wires.
