EiceDRIVER™ with Slew-Rate Control

Overview

Single-Channel Gate Driver Family with Dynamic Slew-Rate Control and Reinforced Isolation

The EiceDRIVER™ SRC family, which includes  1EDS20I12SV,  1EDU20I12SV, and  1EDI20I12SV, serves the latest generation of highly efficient low-EMI electric drive systems with lower EMI and improved efficiency. Evaluation board available:  EVAL-1EDS20I12SV. 
 
Based on our coreless transformer technology, it is the first high-voltage isolated gate driver on the market with dynamic Slew-Rate Control (SRC) which allows on-the-fly dV/dt control of electric drives through precise gate current control, providing the best trade-off between minimum power dissipation and minimum EMI depending on operating conditions.
 
The 1EDx20I12SV family is tailored for industrial drive applications, such as those using 1200-V power modules with currents up to 900 A like the  EconoDUAL™ 3. The driver meets today’s long-term stability requirements for industrial applications. It is offered in a DSO-36 package with a package width of 300 mil. It is RoHS compliant, green, and halogen-free.
