Description  
VBG08H is a single channel driver, plus an IGBT  
power stage internally assembled using Chip On  
Chip (COC) hybrid technology.  
The two chips are assembled together in the  
OctaPAK® package.  
Features  
The device comes with several built-in protections  
like a coil current limiter, thermal monitoring  
circuit, which triggers a Soft Shut Down (SSD) as  
soon as the maximum allowable temperature is  
reached (TSD). It avoids extra voltage on the  
secondary side of the coil transformer.

The Slow Turn On circuit (STO), avoids unwanted  
sparks during first negative dV/dt of HVC voltage  
at turn on.  
Smart electronic ignition with embedded IGBT  
power stage  
The current flag circuit provides an output logical  
signal voltage when the coil current reaches a  
fixed threshold.
