There is no maximum output current specification for MAX12930/1. The "Absolute Maximum Ratings" table shows the output may be continuously shorted to GND; however, the maximum output current will be limited by the source resistance of the output channel.
The DC electrical characteristics show VOH and VOL measurements were tested with 4mA load with a worst case voltage 400mV from the rail. It is likely that the outputs can handle more current, but the maximum sink and source current is not specified.
