DESCRIPTION

The VB026SP 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

VB026SP to be used as a smart, high voltage,

high current interface in advanced electronic

ignition systems.
