Method and apparatus for checking an electrical circuit, in particular an ignition circuit of a motor vehicle occupant protection system
1998
When the switches (11, 13) which are series-connected with the ignitor are tested, the maximum current flowing through each switch being tested is limited to a value which is insufficient for igniting the ignitor (12), even in the event of a leak. The current is preferably restricted by reducing the switch gate voltage while the switches are being tested.
