The Infineon SPIDER family has nine new enhanced high-side / low-side (HS/LS) members. They are all eight-channel SPI-controlled combined high- and low-side switches especially designed to drive automotive relays. The HS/LS family consists of three sub-families (-SL, -SE and -EM), offering different combinations of current capability and package size. Within these sub-families, the devices offer limp-home or low-voltage cranking (down to 4.0V) functionality. The subfamily devices are pin-compatible.
