This document introduces the SCALE driver developed by ABB Switzerland AG, which is based on a chip set specifically developed for reliable driving and safe operation of IGBTs and power MOSFETs. The SCALE series drivers have the outstanding properties of scalability, compactness, versatility, low cost, and ease of use. They are suitable for various applications, including inverters, motor drive technology, traction, converters, power engineering, switched-mode power supplies, radiology and laser technology, DC/DC converters, research, and RF generators and converters.
This manual introduces the SCALE driver series, a chip set designed for reliable driving and safe operation of IGBTs and power MOSFETs. It explains the driver’s key properties—Scaleable, Compact, All‑purpose, Low‑cost and Easy‑to‑use—and lists typical applications such as inverters, motor drives, railroads and power engineering.
The document covers mode selection (direct and half‑bridge), voltage supply requirements, pin functions, connection guidelines for IGBTs, turn‑off threshold setting, and includes a 30 kW inverter example. It also describes evaluation boards, data‑sheet availability, and how to request customized drivers.
| Gate current range | +6 A to +30 A |

SCALE stands for Scaleable, Compact, All purpose, Low cost and Easy to use.
The driver can operate in direct mode or half‑bridge mode.
Both VDD and VDC should be connected to a stabilized 15 V supply.
The driver provides a gate current from +6 A up to +30 A.
