DESCRIPTION
The VB027BSP is a high voltage power integrated
circuit made using the STMicroelectronics
VIPower™ 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
