Single Lamp Driver IC

This ASIC provides up to 350 mA 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

active–low output which reports in the output–on mode. Internal

pull–up circuitry is provided to ensure the output pin turns on when the

Control pin is floating.
