Functional Description
NCS
Chip Select input for the SPI interface. This signal is low active. An internal weak pull-up device to VCC1 drives this
input to High state in case the pin is floating.
IREF1
Reference input of the primary chip. This pin shall be connected to VGND1 via an external resistor.
NRST/RDY
Open drain reset input. This signal is low-active. When a valid signal is received on this pin, the device is brought
in its default state. This signal is also used as a âready notificationâ. A high level on this pin indicates that the
primary chip is functional.
2.2.2.2 Secondary Side
VEE2
Negative power supply for the secondary side, referring to VGND2.
VCC2
Positive power supply for the secondary side, referring to VGND2.
GND2
Reference ground for the secondary side.
DESAT
Desaturation Protection input pin. The function associated with this pin monitors the VCE voltage of the IGBT. An
internal pull-up resistor to VCC2 drives this signal to High level in case it is floating.
OCP
Over Current Protection input pin. The function associated with this pin monitors the voltage across a sensing
resistance located on the auxiliary path of a Current Sense IGBT. An internal weak pull-up resistor to the internal
5V reference drives this input to High state in case the pin is floating.
OCPG
Over Current Protection Ground.
TON
Output pin for turning on the IGBT.
TOFF
Output pin for turning off the IGBT.
GATE
Input pin used to monitor the IGBT gate voltage.
