PRINCIPLE OF OPERATION
The VB025SP is mainly intended as a high voltage power switch device driven by a logic level input and interfaces directly to a high energy electronic ignition coil. The input Vin of the VB025SP is fed from a low power signal generated by an external controller that determines both dwell time and ignition point. During Vin high (≥ 4V) the VB025SP increases current in the coil to the desired, internally set current level. After reaching this level, the coil current remains constant until the ignition point, that corresponds to the transition of Vin from high to low (typ. 1.9V threshold). During the coil current switch-off, the primary
