CONFIGURATION OF DIGITAL DRIVER OUTPUTS

The digital outputs SLO and NSLO can be used as ei-

ther a push-pull, lowside or highside driver. The mode

of operation is determined by DTRI. The driving capa-

bility is set via the short-circuit current parameter.

In order to meet RS422 specifications a short-circuit cur-

rent of 50 mA should be selected as well as to reduce

the internal power dissipation. The driving capability

can be reduced when external line drivers are used.

In order to reduce crosstalk and to improve EMC the

slew rate can be selected to suit the line length. If

the edge steepness is reduced to 300 ns the maxi-

mum permissible transmission frequency is limited to

ca. 300 kHz if RS422 specifications are to be adhered

to.
