2SP0115T Description & Application Manual
Driver solution for EconoDUALTM IGBT modules with an electrical interface with
paralleling capability
Abstract
The 2SP0115T is a dual-channel driver with an electrical interface. The driver is based on CONCEPT’s SCALE-2
chipset, a highly integrated technology for the reliable driving and safe operation of IGBTs.
Perfectly matched driver versions are available for all EconoDUALTM IGBT modules. The plug-and-play
capability of the driver allows immediate operation after mounting. The user needs invest no effort in
designing or adjusting it to a specific application.

2SP0115T
Description and Application Manual
www.DataSheet4U.com
System Overview
The 2SP0115T are plug-and-play drivers based on the highly integrated SCALE-2 chipset developed by
CONCEPT /1/. This is a set of application-specific integrated circuits (ASICs) that cover the main range of
functions needed to design intelligent gate drivers. The SCALE-2 driver chipset is a further development of the
proven SCALE technology /2/.
The basic topology of the 2SP0115T driver is shown in Fig. 2. The values for the gate resistors and other key
components can be found in the specific datasheets for a given IGBT module /3/.

Fig. 2 Basic schematic of the 2SP0115T driver
The driver contains all necessary components for optimal and safe driving of the relevant IGBT module:
smallest gate resistors in order to minimize switching losses, gate clamping, active-clamping diodes
(overvoltage protection at turn-off), Vce monitoring (short-circuit protection) as well as the input electrical
connector X1. Moreover, it includes components for setting the turn-off trip level, the response time and the
dead time between both channels in half-bridge mode. Its plug-and-play capability means that it is ready to
operate immediately after mounting. The user needs invest no effort in designing or adjusting the driver to a
specific application.
