Gate-drive isolator for inverter and motor-drive stages
It is designed to drive the gate of IGBTs or power MOSFETs in half-bridge and full-bridge topologies, with a 2500Vrms isolation barrier between the input logic side and the output gate-drive side. The output supply rail spans 12V to 18V, matching the typical bias voltage for IGBT gate drivers in motor drives, inverters, and industrial power supplies.
75kV/µs CMTI — keeps data through fast switching edges
Common-mode transient immunity is rated at a minimum of 75kV/µs, which means the isolator holds its output state when the ground plane between primary and secondary bounces during a hard-switching event. In a motor-drive or solar-inverter environment where the IGBT collector swings hundreds of volts in tens of nanoseconds, this CMTI rating prevents bit errors that could cause a shoot-through. The 160ns maximum propagation delay (both directions) and 8ns pulse-width distortion give the designer a predictable dead-time budget to work with when sizing the switching interval between high-side and low-side devices.
100mA peak output — enough for standard IGBT gates
Each of the two channels delivers a peak output current of 100mA, which is sufficient to drive the gate capacitance of medium-power IGBTs (typically 10nC to 50nC total gate charge) at switching frequencies up to several tens of kilohertz. For larger modules or higher frequencies, an external booster stage may be needed. The rise and fall times are both 25ns typical (max), keeping the switching edges clean without excessive ringing.
Package and temperature grade for industrial environments
The package is ROHS3 compliant, and the part carries UR and VDE safety approvals, which simplifies the certification paperwork for the end equipment.
Active lifecycle — no near-term obsolescence pressure
The iCoupler series is a mature platform with broad second-source options within the family, though no pin-compatible alternate is listed on this record.
