Abstract

<P>PROBLEM TO BE SOLVED: To provide a means capable of effectively protecting a rechargeable element. <P>SOLUTION: A protection circuit for use with a charger and a chargeable element, such as, a rechargeable lithium ion battery includes a shunt regulator having a threshold ON voltage, coupled in parallel between both ends of the chargeable element; and a temperature-dependent resistor, for example, a positive temperature coefficient device, coupled in series between the charger and the chargeable element. The temperature-dependent resistor is coupled thermally and electrically to the shunt regulator. A first variable resistor limits the current, if the current running through the shunt regulator reaches a predetermined level lower than that which would cause failure of the regulator, due to ohmic heating of the regulator. <P>COPYRIGHT: (C)2009,JPO&INPIT
