Compact, high-quality, low-cost high-power IGBT driver

Highly integrated SCALE-2 technology

35A gate current and 2 x 4W output power

Short Description

The new high-power low-cost SCALE-2 dual driver core 2SC0435T combines unrivalled compactness with broad applicability. The driver has been designed for universal applications requiring high reliability and performance. The 2SC0435T drives all common high-power IGBT modules up to 1700V. The embedded paralleling capability allows easy inverter design covering higher power ratings. Multi-level topologies are also supported.

Advantages of the Technology

The 2SC0435T is the most compact driver core in its power range, featuring a footprint of only 57.2 x 51.6mm and an insertion height of 20mm. It allows even the most restricted insertion spaces to be efficiently used. Compared with conventional drivers, the highly integrated SCALE-2 chipset allows about 85% of components to be dispensed with. This advantage is impressively reflected in increased reliability at simultaneously minimized cost.

The 2SC0435T combines a complete two-channel driver core with all components required for driving, such as short-circuit protection, advanced active clamping, an isolated DC/DC converter as well as supply voltage monitoring. Each of the two output channels is electrically isolated from the primary side and the other secondary channel.

IGBT Mode

An output current of 35A and 4W drive power is available per channel, making the 2SC0435T an ideal driver platform for both high-power modules and parallel circuits. In the dedicated IGBT mode, the driver provides a gate voltage swing of +15V/–10V. The turn-on voltage is regulated to maintain a stable 15V regardless of the output power level.

Its outstanding EMC allows safe and reliable operation in even hard industrial applications. The 2SC0435T is suited for high-power IGBTs with blocking voltages up to 1700V.

MOSFET Mode

A dedicated MOSFET mode is implemented in the 2SC0435T. It allows any gate voltage swing of +10V…+20V/0V to make the most of the driver’s 100kHz switching speed.

With the high output power, very short delay, and small jitter, the 2SC0435T driver core has been specifically designed for high-power and ultra-fast switching to fully exploit the capabilities of state-of-the-art MOS power devices.
