Yes, Power Manager II device supports Hot Socketing. All the pins of the Power Manager II are Hot Socket complaint. There is no problem in applying maximum specified I/O voltages to the pins before VCCD or VCCA is applied. However small leakage ...
The LatticeECP3 doesn't have a dedicated control signal to put the FPGA IO to tri-state. There are cases that some designers might want to have the LatticeECP3 FPGA IO tri-stated when a new line card is being inserted as some partner devices in these ...
First of all, only the dash-two (POWR1220AT8-2) Power Manager devices support HVOUT output voltage of 12V. Secondly, the gate of the hot swap MOSFET does need to be driven to 18V to 20V in order to turn it on. This is accomplished using a few ...
