DRIVE DEVICE

摘要

A drive device according to one aspect of the disclosure includes a control terminal connector, a switch circuit, a current limit circuit, and a clamp switch on a circuit board. The clamp switch is located in a second quadrant or a fourth quadrant of four quadrants, where the four quadrants are partitioned by two mutually orthogonal virtual lines with the current limit circuit set as an origin and the four quadrants consist of a first quadrant including an area where the control terminal connector is located, the second quadrant, a third quadrant, and the fourth quadrant, in clockwise order.

1. A drive device comprising:
a circuit board; a first potential line that provides first potential, the first potential line being located on the circuit board; a second potential line that provides second potential lower than the first potential, the second potential line being located on the circuit board; a control terminal connector that is located on the circuit board and that is connected to a control terminal of a power switch; a switch circuit that selectively switches whether electric charge is to be supplied to the control terminal of the power switch or is to be drawn from the control terminal of the power switch, the switch circuit being connected between the first potential line and the second potential line on the circuit board; a current limit circuit that is connected between the switch circuit and the control terminal connector on the circuit board; and a clamp switch that is connected between a conductive path, which extends between the control terminal connector and the current limit circuit, and the second potential line on the circuit board, wherein the clamp switch is located in a second quadrant or a fourth quadrant of four quadrants on the circuit board, where the four quadrants are partitioned by two mutually orthogonal virtual lines with the current limit circuit set as an origin and the four quadrants consist of a first quadrant including an area where the control terminal connector is located, the second quadrant, a third quadrant, and the fourth quadrant, in clockwise order.
