U6820BM-MFPG3

U6820BM-MFPG3 Datasheet

The U6820BM is a driver interface in BCDMOS technology with 8 independent driver stages having a maximum current capability of 50 mA each. Its partitioning into 4 high-side and 4 low-side driver stages allows an easy connection of either 4 halfbridges or 2 H-bridges on the pc board. The U6820BM communicates with a microcontroller via an 8-bit serial interface. Integrated protection against short circuit and overtemperature give added value. EMI protection and 2-kV ESD protection together with automotive qualification referring to conducted interference ISO/TR 7637/1 make this IC ideal for both automotive and industrial applications.
