PROBLEM TO BE SOLVED: To provide a voltage monitoring module and a voltage monitoring system capable of performing disconnection detection within a short time.SOLUTION: A voltage monitoring module 100 includes diodes D1 to Dm-1 connected between two adjacent input terminals and configured to supply current when the voltage of a k-th input terminal is larger than that of a (k-1)-th input terminal, and a disconnection detection circuit 10 for detecting disconnection between battery cells EC1 to ECm, and m input terminals. The disconnection detection circuit 10 includes an activation circuit 13 for controlling current flowing between m input terminals and a ground terminal VSS. The disconnection detection circuit 10 further includes PMOS transistors P_1 to P_m-1 having one end connected to the second to the m-th input terminal, a control terminal connected to the first to (m-)-th input terminals, and turned ON when a voltage applied to the control terminal is smaller than a predetermined value, and a register 12 connected to the drains of the PMOS transistors P1 to Pm-1. |
