BCD OFF LINE TECHNOLOGY The high level of integration of the L6590 family is made possible by the BCD OFF LINE technology Compared to other high voltage technologies BCD allows more design flexibil ity due to the large variety of components available: n high voltage N channel LDMOS 700V n medium voltage bipolar transistor 20V both NPN and PNP type n low and medium voltage CMOS devices to 10V n zener voltage references n resistors and capacitors Figure BCD Off line Cross Sections
