Load control device and method |
摘要 |
A load control device includes a control circuit and a protection circuit. The control circuit controls driving of an electric load. The protection circuit monitors a power supply voltage supplied to the control circuit and stops control of driving the load by the control circuit, when the power supply voltage drops below a threshold value. The protection circuit provides the threshold value with a hysteresis characteristic having a width determined by a product of a wiring resistance of a path for supplying a driving current to the load and a maximum value of the driving current.
