... 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 ...

... The detection of overtemperature is latched internally reset by the falling edge of the 4 clock (bit data transfer if overtemperature is no longer present. 4527B–BCD–09/ clock. The reset is initiated by the falling edge of the 2 U6820BM control bit. The priority protects the IC against th clock (bit 7) of the next data nd clock (bit 1) of the next ...
