Abstract
A current detection device includes a main busbar and a semiconductor chip. A detected current flows through the main busbar. The semiconductor chip is spaced apart from the main busbar. The semiconductor chip includes a branch busbar, a detection part, and an output part. The branch busbar is connected in parallel with the main busbar. The detection part is arranged adjacent to the branch busbar and detects a first magnetic field generated based on a branch current flowing from the main busbar to the branch busbar. The output part calculates and outputs a current value based on the first magnetic field detected by the detection part.
