Description
The VB025SP is a high voltage power integrated circuit made using STMicroelectronics VIPower Technology, with vertical current flow power darlington and logic level compatible driving circuit. Built-in protection circuits for coil current limiting and collector voltage clamping allows the VB025SP to be used as a smart, high voltage, high current interface in advanced electronic ignition systems. ® March 1999 BLOCK DIAGRAM TYPE Vcl Icl Id VB025SP 380 V 9 A 100 mA 1 10 PowerSO-10 1/7
