Infineon Technologies AG has developed the 2EDL EiceDRIVER compact half-bridge gate driver geared for applications with a blocking voltage of 600V. According to the company, the device is equipped with a very fast bootstrap diode and resistor, and features components that enable high efficiency in a very compact construction.

The driver is intended for space-saving installations in consumer electronics as well as household appliances. They can also be used in fans, pumps, engines and forklifts. The family of driver ICs, designed for use with power semiconductors such as in the newest CoolMOS generation, exhibit improved switching behavior that reduces energy loss in a multitude of power applications, added the company.

The seven devices in the 2EDL EiceDriver compact class are designed for IGBTs as well as with MOSFETs. They are available in DSO-8 and DSO-14 packages. The output current for the devices is set to 0.5A or 2.3A. With the integrated low-resistance and very fast bootstrap diode, the 2EDL EiceDRIVER sets new standards in the market of driver ICs with more than two amp output current strength, boasted the company. The bandwidth of the EiceDRIVER range enables a variety of applications. Driver ICs in the DSO-14 assembly also have extended creepage. This means they meet requirements for higher protection classes and can even be used in industrial applications.

The level-shift in the EiceDRIVER compact series is based on Silicon-on-Insulator technology. This places the active transistor layer on the top of an insulator, which results in outstanding robustness against latch-up effects when the component is exposed to extreme temperature and voltage conditions. In a latch-up effect, a semiconductor enters an uncontrolled low-resistance state. This can lead to a short circuit or thermal overload and destroy the component. In addition, the coreless transformer technology introduced by Infineon will also be available for the compact class. This makes faster switching operations possible with-out any loss of performance, Infineon noted.

Samples of the 2EDL EiceDRIVER compact class are in stock. A corresponding customer evaluation board can be ordered now and will be available within the next few weeks. Products can be ordered starting in August 2013.
