The squib driver can stand the short to ground of the pins during the deployment, because the High Side current is limited by the High Side itself. It can also manage the case of SRx short to ground after an open circuit, because it is able to detect the open circuit condition and ...
The presence of major automotive manufacturers and their commitment to electrification strategies has been a key driver for market growth. The European Union's ambitious environmental goals and stringent safety regulations have created a favorable environment for pyro fuse applications. The region's focus...
Deployment driver protection In order to avoid damaging the IC due to eventual free-wheeling, two protections are implemented: • After a deployment, once the High Side is switched off, the Low Side is kept on for tDEL_SD_LS (50 μs min.) in order to allow fly-back. • Once Low...
