1ED3491MU12M

Overview

5.7 kV, 9 A single-channel flexible isolated gate driver with active Miller clamp, adjustable DESAT and Soft-off. UL 1577 certified

EiceDRIVER™ Enhanced 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.

1ED3491MU12M belongs to the EiceDRIVER™ Enhanced 1ED34xx family (X3 analog family). 1ED3491 offers high configurability with DESAT (adjustable filter time), and soft-off (adjustable current level), through external resistor from input side (ADJA and ADJB pin). The driver IC also offers separate output, active Miller clamp (clamp driver for external MOSFET), Fault, and over temperature shutdown.

1ED3890xx (X3 digital) version available, with I2C configurability for up to 14 parameters.
