... Functional Description (1) 2-channel squib drive function Using independent four-channel inputs, this IC controls two high-side and two low-side switches, making it possible to drive two squibs directly. (2) Squib line short-to-battery, short-to-ground and open-circuit diagnostic function (diagnostic voltage output) When the squib is in normal state external diagnostic resistor, the device outputs a voltage derived from V by dividing it according to the resistance ratio ...
