![]() Two more permitted controlling 7 MOSFETS and one SSR with a tiny footprint of 1" x 2" x 3/4" including 33 wires for all three boards. ![]() This allowed me to have two encoders on one chip. Control response went from 97% - 99.9% range to 74% - 99.9%, giving tremendous improvement.Īnother feature is the bidirectional function of all ports. This MOSFET controls large 12vdc coils for a hydraulic valve. In fact bandwidth of transmitted PWMs has almost tripled. These have one more use for us, We originally tried to drive some high power MOSFETs with poor response, but after adding pull up resistors to the gates, and IO static with a pull down resistor set internally on the pin, we get very reliable control. ![]() While these were built to translate the voltage levels of TTL data streams, I found additional applications, such as MOSFET driver to isolate the sensitive IO ports on our Beaglebone Blacks, bring raw encoder outputs down from 5 to 3v3, isolate a high voltage SSR from the IO's and raise the input from 3v3 to 5v for more positive actuation.
