Functional Description

SDI

Serial Data Input for the SPI interface. An internal weak pull-up device to VCC1 drives this input to high state in

case the pin is floating.

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 “ready notification”. 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.
