Description
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 half-
bridges or 2 H-bridges on the pc board. The U6820BM communicates with a micro-
controller 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.
