1ED3461MC12M
6 A, 5.7 kV single-channel flexible isolated gate driver with active Miller clamp, adjustable DESAT and Soft-off. UL 1577 & VDE 0884-11 certified
EiceDRIVER™ Enhanced single-channel highly flexible isolated gate driver with ±6 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.
1ED3461MC12M belongs to the EiceDRIVER™ Enhanced 1ED34xx family (X3 Analog family) – single-channel isolated gate driver with adjustable DESAT and soft-off. Suitable for IGBTs, MOSFETs and SiC MOSFETs. 1ED3461 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, Fault, and over temperature shutdown.
I2C経由でアクセス可能な27のコンフィギュレーション レジスタを備えた1ED3860* (X3 Digital) バージョンも提供しています。
