Tamura's New Gate Driver Module Integrates the Functions Required for the SiC MOSFET and IGBT Gate Drivers

By Rob GrayMay 12, 2016

Tamura introduces its new Gate Driver Module, the DM Series. The driver module series checks all boxes as far as the functionality requirements for insulated-gate bipolar transistors (IGBTs) and silicon carbide (SiC) MOSFETs are concerned.

In particular, Tamura’s next-generation gate driver module specifically emphasizes on common mode noise preventive measures. The new DM series gate drivers also provide the most efficient output drive capability with shortest propagation delay and increased system protection, for isolated power designs and uninterrupted power supplies.

Highlights of Tamura's New SiC MOSFET and IGBT Gate Drivers The Innovative All-in-One Concept

The unique feature of Tamura's new Gate Driver Module is its All-in-One composition. Capable of delivering an incredible output drive by employing only a few external components, the DM series SiC MOSFET and IGBT Gate Drivers packs a built-in DC-DC converter and alongside a drive circuit.

Common Mode Noise Reduction

Imposing check on the common mode noise has been the top priority of Tamura in its DM series gate driver modules. With a stray capacity of around 15pF, including power supply, SiC MOSFET and IGBT Gate Drivers prevents malfunction and damages by restricting the stray capacity limit.

High Response Speed

Another key point of the DM series is its high speed performance. Adopting to magnetic coupling between the primary and secondary signal transmission, the gate driver generates a blazing speed response with a delay time of just 100 nsec.
