ACCELERATION SENSOR ARRANGEMENT, SAFING ARRANGEMENT FOR AN ACTIVATION SYSTEM, ACTIVATION SYSTEM

摘要

An acceleration sensor arrangement comprises, in one package, an acceleration threshold detector for detecting acceleration and for providing an output signal and a processor circuit for receiving the output signal. The acceleration threshold detector provides an output signal having a first value when the acceleration is less than a predetermined threshold and is arranged to switch the output signal from the first value to a second value when the acceleration reaches the predetermined threshold. The processor circuit generates an event signal to trigger an event, such as the closing of a safing transistor switch in an airbag system, in response to the output signal from the acceleration threshold detector switching to the second value.
