Abstract:
1. An end-of-service-life integrated circuit chip (IC 2 ) capable of performing an end-of-service-life test in a circuit interrupting device, said IC 2 comprising: a flip-flop latch circuit comprises a first transistor and a second transistor; wherein said flip-flop latch circuit is adapted to receive and transmit a status signal when said circuit interrupting device is powered on and at a tripped state, allow said circuit interrupting device to be reset when components in a main circuit of said circuit interrupting device function normally, and disallow said circuit interrupting device to be reset when at least one of said components in said main circuit of said circuit interrupting device do not function properly; and an emitter circuit comprising a third transistor; wherein said emitter circuit is adapted to output said status signal from said flip-flop latch circuit through said third transistor to a simulated leakage current generation circuit of said circuit interrupting device to generate a simulated leakage current to test whether said components in said main circuit of said circuit interrupting device function normally; and wherein said IC
