1. A fusion bonding protecting module configured to control a negative contactor connected between a negative electrode of a battery pack and a second output end according to fusion and bonding of a positive contactor connected between a positive electrode of the battery pack and a first output end, comprising:
a set/reset (SR) latch including a set terminal configured to receive a fusion bonding sensing signal according to whether the positive contactor is fused and bonded and a reset terminal for receiving a comparison signal according to a voltage difference between a first end and a second end of the positive contactor; and
an AND gate configured to generate a compensation control signal in response to receiving both a logic control signal that is an inverted output of the SR latch and a control signal for controlling the negative contactor.
