Terminating resistance setting circuit and battery management system including same

A terminating resistance setting circuit provided in each of a plurality of communication devices that perform communication in a differential input mode, the terminating resistance setting circuit comprising:

• a resistance generation unit connected between a pair of communication lines for differential input to generate a terminating resistance;
• a first control circuit that applies a first control signal to the resistance generation unit;
• and
• a second control circuit formed between the resistance generation unit and a reference potential and controlled to apply a voltage according to the reference potential to the resistance generation unit by a second control signal,
• wherein the first control signal is a second control signal transmitted by another communication device among the plurality of communication devices that communicates with a first communication device among the plurality of communication devices in which the terminating resistance setting circuit is formed.
