im trying to use an pcf8574 to drive 8 mosfets. each mosfet runs a 12v 2.5watt motor. i need to run all motors at same time. it seems like each mosfet needs at least 200-250ma to fully saturate. the pcf8674 can only source 100ma and i think i fried it when i tried to power on all the mosfets.
can someone help me choose the right parts to make this work.
pcf8574 datasheet say can source 100ma. its this combined or per output?
