VBG08H-E

STMICROELECTRONICS  VBG08H-E  芯片, 点火线圈驱动器, 28V, OCTAPAK-7

The is a 1-channel Driver plus an IGBT power stage internally assembled using Chip On Chip COC hybrid technology. 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.
