CS1108

CS1108 CS1108 Single Lamp Driver IC Description This ASIC provides up to 350mA of drive current for powering bulbs. The typical application for this part is for use in airbag systems using a type 194 bulb. On chip diagnostics provide open circuit and short circuit detection in the output on mode. In addition, the output driver will turn on (sink current) when VCC is low. Fault is an active-low output which reports in the output-on mode. Internal pullup circuitry is provided to ensure the output pin turns on when the Control pin is floating.
