Abstract
A semiconductor device, a battery monitoring system, and a detection method are provided. An end of the capacitor (C) is switchable to be connected to one of a positive electrode and a negative electrode of a battery cell. An end of a capacitor (C) is switchable to be connected to the other electrode. A comparator includes a non-inverted input terminal connectable to the battery cell via the capacitor (C), and an inverted input terminal connectable to the battery cell via the capacitor (C). A capacitor (C) is located between a node (inp) and a switch (S) that switches a connection state between a ground voltage source and any one of reference voltage sources. A capacitor (C) is located between a node (inn) and a switch (S) that switches a connection state between the ground voltage source and any one of the reference voltage sources.
