DESCRIPTION
The VB029, VB029SP, VB029(011Y)
VB029(012Y) are a high voltage power integrated
circuit designed in STMicroelectronics VIPowerâ¢
technology, with vertical current flow power
darlington and logic level compatible driving
circuit. Built-in protection circuit for coil current
limiting and collector voltage clamping allows the
device to be used as smart, high voltage, high
