Figure 5
The connector X202 (see Figure 5) connects the daughter board with all signals from the primary side (low-
voltage side) of the gate driver, like IN+, IN-, /Fault, /RDY, VCC1 and GND1 of both drivers to the evaluation
platform and the corresponding connector X100 on this platform
As interface to the power switches acting the connectors X200 and X201 (see Figure 5) with the gate signal, the
source connection and the drain connection for the DESAT function. Connector X200 serves the high-side
switch, X201 the low-side switch. At the same time, the respective supply voltages for the drivers ( VCC2, VEE2
and GND2) are connected.
