An overcurrent interrupting device includes a power MOSFET ( ) for controlling an electric current flowing from a power supply to a load; a current detection circuit ( ) for detecting a current value of an electric current flowing from the power MOSFET ( ) to a load (L); a determination value selection circuit ( ) for selecting a determination value used for determining an overcurrent; an overcurrent determination circuit ( ) for determining whether or not the current value represents occurrence of an overcurrent, on the basis of the current value detected by the current detection circuit ( ) and the determination value selected by the determination value selection circuit ( ); and a boosting and switching circuit ( ) for controlling activation/deactivation of the power MOSFET ( ) on the basis of a result of determination rendered by the overcurrent determination circuit ( ).

Overcurrent interrupting device

In a semiconductor relay system for supply a power source to a lamp load under the on/off control by a microcomputer using a semiconductor relay, a method of cutting off a circuit under an overcurrent, a first prescribed value is which is a current value higher than a rated load current for the load and a maximum current value supplied to the lamp load, and a second prescribed value is set which is a current value between said first prescribed value and said rated current value; the current value flowing through the lamp load is sampled at predetermined time intervals and comparing the current value thus sampled with the second prescribed value; and when a higher current than said first prescribed value flows through the lamp load, the current supplied to the lamp load is controlled within a prescribed range between said first prescribed value and said second prescribed value, and when the sampled current value higher that said second prescribed value is counted by a prescribed number of times, the sampled current is decided as an overcurrent thereby cutting off the semiconductor relay to stop the current supply to said lamp load.

Thermoplastic resin composition and molded product thereof

A multiplex transmission system in a vehicle, for transmitting data indicating an on/off state of an ignition switch, includes first and second power distributing units receiving first and second signals over first and second signal lines, respectively, indicating the on/off state of the switch. The first power distributing unit controls a first load in accordance with the on/off state of the switch indicated by the first signal. The first power distributing unit provides a third signal to the second power distributing unit over a multiplex transmission line indicating the on/off state of the switch. When either the second signal or the third signal indicates that the switch is in an on state, the second power distributing unit controls the second load in accordance with the on state of the switch. When the second power distributing unit fails to receive the third signal, the second power distributing unit controls the second load in accordance with the on/off state indicated by the second signal.
