CISSOID has launched the second generation of its HADESTM isolated gate driver, a highly integrated solution designed for high-density power converters, motor drives, and actuator applications. This advanced product is optimized for use with fast-switching silicon carbide (SiC) transistors, conventional power MOSFETs, and IGBTs. Known for their exceptional durability, CISSOID's products ensure higher reliability and longer lifespan in challenging environments, making them ideal for aerospace, automotive, industrial, oil, and gas sectors.

HADES? comes in both hermetic ceramic and plastic packages. The ceramic version is suitable for extreme temperature applications up to 225°C, while the plastic variant is ideal for systems operating up to 175°C but with an emphasis on extended service life.

The HADES® v2 gate driver offers a complete, highly integrated solution for driving power switches in isolated high-voltage half-bridges. This compact design fully leverages the benefits of fast-switching SiC transistors, enhancing efficiency and performance in power electronics systems.

The chipset consists of three key components: the HADES2P on the primary side, the HADES2S on the secondary side, and the newly introduced four-diode ELARA. Both the primary and secondary chips are available in ceramic QFP 32-pin or plastic QFP 44-pin packages, offering flexibility for different application needs.

The primary-side chip (HADES2P) features an integrated 0.8 ohm-80V switch, along with configurable non-overlapping and undervoltage lockout (UVLO) fault management functions. It also includes a four-channel isolated signal transceiver (2 Tx and 2 Rx) for transmitting PWM and fault signals from the secondary side through a compact pulse transformer.

The secondary-side chips (HADES2S), one for high-side and one for low-side, include a 12A driver, UVLO, desaturation, and over-temperature protection (OTP) fault detection circuitry, as well as a dual-channel isolated signal transceiver. This ensures robust and safe operation under various conditions.

HADES® v2’s thermal durability allows designers to place gate drivers close to power transistors, minimizing parasitic inductance and enabling faster switching with reduced switching losses. Lower switching losses lead to higher operating frequencies, which in turn reduce the size and weight of capacitors and magnetic components. Additionally, higher operating temperatures mean lower cooling requirements, resulting in a more compact and efficient system overall.

The HADES® v2 chipset is optimized to minimize the number and size of active and passive components, making it ideal for integration into Intelligent Power Modules (IPMs). When the gate driver is placed next to the power switch, this integration increases the power density of the converter, ensuring reliable long-term operation at high temperatures—several years of service in applications ranging from 100°C to 175°C, or thousands of hours at extreme temperatures between 175°C and 225°C.

Mr. Tony Denayer, CEO of CISSOID, said, “HADES® v2 is the result of three years of collaboration with system manufacturers and end users across various industries, including motors for industrial applications, rail-oriented auxiliary converters, aerospace generators, and HEV/EV battery chargers. We’ve gathered insights from experts who worked on the first version of HADES, which was released in 2011 as the first isolated gate driver solution for fast-switching SiC power components.”

HADES® v2 is not only suited for harsh environments but also for large-scale, cost-sensitive applications where ambient temperatures do not exceed 100°C. Its focus on longevity and maintenance costs makes it a compelling choice for a wide range of applications.

In summary, HADES® v2 opens the door to true high-density power converters. Many of our customers are eager for its launch, and we are proud to introduce this groundbreaking technology to the market.

The HADES® v2 datasheet can be found on the CISSOID website at: http://Gate-driver-for-high-density-power-converters-chipset.html. Hermetic ceramic chipsets are available for immediate delivery, while the plastic version is available for order with samples expected in June 2015. The evaluation kit (p/n: EVK-TIT2785A-T) is currently available for purchase at €3,300.
