DESCRIPTION

The VB025BSP 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 VB025BSP to be used as a smart, high voltage, high current interface in advanced electronic ignition systems.

■ PRIMARY COIL VOLTAGE INTERNALLY SET

■ COIL CURRENT LIMIT INTERNALLY SET

■ LOGIC LEVEL COMPATIBLE INPUT

■ DRIVING CURRENT QUASI PROPORTIONAL TO COLLECTOR CURRENT

■ SINGLE FLAG-ON COIL CURRENT
