A series current regulator with an on-silicon temperature sensor (102) formed over current battery protection device (100). The protection device (100) regulates current in a pass element (101) linearly while sensing the junction temperature of the pass element (101). If the temperature of the pass element (101) reaches a predetermined threshold, the on-silicon temperature sensor (102) actuates a switch (104) which causes the pass element (101) to go into a high impedance mode. The protection device offers advantages over positive temperature coefficient (PTC) and further includes faster trip time and lower leakage current.
