Hardware description and configuration

The STGAP1AS features an SPI interface that is used to set the device parameters, enable

or disable the device functions and for advanced diagnostic. However for an easy device

evaluation it is also possible to operate the STGAP1AS without using the SPI interface. In

this case the driver works with default configuration values and protections. For more details

refer to Section 3.1: Using EVALSTGAP1AS in standalone mode on page 10.

Name

Type

Function

J1

Board extension connector Used to connect an optional slave EVALSTGAP1AS board.

J2

Power supply connector

Used to feed supply voltage VH and optional negative supply

voltage VL to the gate driving side.

J3

Control signals connector

Used for control (logic inputs and fault signals interfacing).

J4

Control signals connector

Used for the STGAP1AS SPI and diagnostic interfacing.

Connector is suitable for interfacing to the

STEVAL-PCC009V2 universal interface board.

J5

Board extension connector

Used to connect the master EVALSTGAP1AS board in 2-

board configuration.

J6

Power supply connector

Used to feed supply voltage VDD to the logic control side.

C plate Load connection

A plate hole for the load current input path (IGBT collector).

E plate Load connection

A plate hole for the load current output path (IGBT emitter).
