Max source / sink for SX28

Hello,
I've read that the maximum source & sink capability is about 30ma per pin, but what is the max draw?· Is it possible to draw 600ma (20 pins * 30ma) without melting the chip?· Could this be done safely at a 20% duty cycle?· Thanks.

    The absolute max source or sink current via the supply pins is only 130mA. I think you'll need to find an appropriate external circuit to power whatever you need...
