14 Claims

1. An electronic unit with a substrate, the electronic unit comprising:

a control circuit mounted on the substrate and configured to execute a control operation related to a load;

a package encapsulating the control circuit and the substrate, the package having a plurality of surfaces around a periphery of the substrate;

at least one input terminal for input of a signal externally sent to the electronic unit, the at least one input terminal being disposed on at least one of the plurality of surfaces;

at least one output terminal for output of a control signal for controlling the load, the at least one output terminal being disposed on at least another one of the plurality of surfaces; and

at least one check terminal for input/output of a signal for checking at least the control circuit, the at least one check terminal being disposed on at least another one of the plurality of surfaces; wherein

at least another one of the plurality of surfaces on which the at least one check terminal is disposed has a concave portion, and the at least one check terminal is disposed on the concave portion that allows the at least one check terminal not to project from an outline of a portion of at least another one of the plurality of surfaces except for the concave portion.
