Abstract

The airbag squib drivers have the LS_FET operated in R ds_on mode. However to protect the LS_FET against short-to-battery conditions, a current regulation or current limitation is necessary. In this chapter the current regulation of the LS_FET with a senseFET-based current sensing scheme is described. It describes the challenges that are needed to stabilize the LS_FET for the R-L-C loads. The same load conditions applied to the HS_FET apply to the LS_FET. The targeted current limit is 3 A for 2 ms. Similar to the HS_FET, the LS_FET needs energy limitation in the unpowered state in order to prevent inadvertent deployment of the squib.
