VBG08H-E Ignition coil driver power I.C. Datasheet - production data
■ Smart electronic ignition with embedded IGBT power stage
■ Coil current limiter
■ Current threshold flag diagnostic output
■ Enable pin
■ Slow turn-on
■ Soft shut down (SSD) operated by low voltage clamp circuit (LVC)
■ SSD activated by
▲ Thermal intervention (Tj > 150°C)
▲ Enable pin
▲ Input overvoltage
▲ Battery overvoltage
■ Battery fault tolerant pins
■ ESD protected
■ TTL compatible
● 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.
■ 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.
■ The current flag circuit provides an output logical signal voltage when the coil current reaches a fixed threshold.
