VRL, VRH, OUTU, OUTV, OUTW
VRL and VRH inputs are the reference voltages for the OUTx analog output of the current sensors.
VRL is the low voltage rail for OUTx and it is connected to VSS by a 0 Ohm resistor. VRH is the high voltage
rail for OUTx and it is connected to a linear 5V regulator by a 0Ohm resistor.
Both VRH and VRL can be disconnected to the respective supplies (VSS and 5V regulator) in order to be
supplied by the controller board.
OUTx are directly connected to the IR2277S devices output.
Note: further information about IR2277S I/Os are described in details in IR2277S data sheet.
VCC supply pin
This is the supply pin for all the devices. On board a green LED indicates the supply power on; Figure 2b
shows the connection.
Figure 2: LED connection
VSS ground pin (GND)
When stacked together, the board ground is shared among the stack. Gate drivers board share the VSS with
DC- (power ground) with a star connection on DC-.
