9 A, 5.7 kV single-channel highly flexible isolated gate driver with I2C configurability for DESAT, Soft-Off, UVLO, Miller clamp, TLTO, and Fault. UL 1577 & VDE 0884-11 certified

EiceDRIVER™ Enhancedsingle-channel highly flexibleisolated gate driverwith ±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) forIGBTs,MOSFETsandSiC 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.
