1ED3890MC12M 2300 V single-channel highly flexible isolated gate driver with I2C configurability for DESAT, Soft-Off, UVLO, Miller clamp, TLTO and Fault
EiceDRIVER™ Enhanced 9 A, 5.7 kV single-channel highly flexible isolated gate driver with ±9 A typical sinking and sourcing peak output current in small space-saving DSO-16 fine pitch wide-body package with large creepage distance (>8 mm) for IGBTs, MOSFETs and SiC MOSFETs.
1ED3890MC12M belongs to the EiceDRIVER™ Enhanced 1ED38xx family (X3 digital family) – single-channel isolated gate driver with adjustable control and protection functions including DESAT, Soft-Off, UVLO, Miller clamp, two level turn off (TLTO), and Fault, to simplify the design of highly reliable systems. All parameter adjustments are done from the input side via the I2C interface (pin SDA and SCL). 1ED3890 is suitable for IGBTs, SiC and Si MOSFETs.
The digitally configurable approach enable customers for predictive maintenance in sophisticated industrial systems. For example, 1ED38xx is able to register the counts of UVLO spikes, monitor the supply voltage and temperature increase. With the long-term analysis of the collected data, customers are able to decide when is the best time to schedule a maintenance cycle before the system fails. The I2C interface also enables rapid prototyping without hardware changes.
1ED3491 (X3 Analog) version available, with active Miller clamp (clamp driver for external MOSFET), adjustable DESAT and Soft-off.

You will have a glimpse of the different gate driver technologies available at Infineon and their benefits.
For a better understanding we will take a look at the optimization of external gate resistors to drive MOSFETs in a given application.
With this training, you will learn how to calculate a gate resistance value for an IGBT application, how to identify suitable gate driver ICs based on peak current and power dissipation requirements, and how to fine-tune the gate resistance value in laboratory environment based on worst case conditions.
Silicon Carbide MOSFETs bring a lot of opportunities to power electronics. However, how to achieve sufficient system benefits by using Silicon Carbide MOSFETs with suitable gate drivers? This training helps you to learn how to calculate a reference gate resistance value for your Silicon Carbide MOSFET; how to identify suitable gate driving ICs based on peak current and power dissipation requirements; and how to fine-tune the gate resistance value in laboratory environment based on worst case conditions.
