Abstract
The protection circuit unitis an integrated body comprising a surface-mount type PTC thermistormounted by a soldering on a printed circuit boardthrough reflow soldering or the like soldering method together with a protection ICand a FET unit. The surface-mount type PTC thermistor, as compared with a PTC thermistor with leads, can be mounted readily on the printed circuit board, without requiring bending and welding work of a lead to be connected to a negative terminal of prismatic battery cell, for forming a circuit. As a result, change in a resistance due to a bending stress, a thermal stress, etc. can be eliminated. Furthermore, a degree of thermal coupling with the battery cellcan be adjusted by changing a location of the thermistor. Thus, varieties of control functions can be implemented.
