Outputs
The XP8100 high-current outputs normally have “sinking” driv-
ers. The sinking drivers (2803s) are rated at a maximum output
of 48V at 500 mA per individual output (when only one output
is active). You can get sourcing drivers (2985s) by special order.
Each driver chip can, and should, be connected to a “K” line to
prevent inductive kickback current from damaging the drivers.

When all sinking outputs are on simultaneously, thermal limits
restrict the current to 75 mA per output. If the temperature ex-
ceeds 50°C, derate power dissipation by 55°C per Watt.
Jumpers J1 and J3 route the K and GND lines to the drivers, ac-
cording to whether you have sinking or sourcing drivers.
