Dual-channel isolated gate driver for motor drives and inverters
The 5000Vrms isolation rating is the figure that determines whether this part satisfies the reinforced-insulation requirements for motor-drive and inverter designs where the gate-drive signal must cross a safety barrier. The 50kV/µs common-mode transient immunity (CMTI) tells you how well the output side rejects fast voltage transients that appear across the isolation gap — a spec that matters when the lower IGBT switches at tens of kV/µs and you need the gate signal to stay clean. Propagation delay is 59ns max (both edges), which sets the timing budget for dead-time insertion and switching frequency. If your design runs above 100 kHz, that 59ns eats into the available dead-time window, so check it against your controller's PWM timing.
Package and approvals
Housed in a 16-SOIC (0.295", 7.50mm width) surface-mount package, the ADUM4223ARWZ is supplied in tube form. The package carries CSA, UR, and VDE approvals, which simplifies certification for end equipment sold into North American and European markets. ROHS3 compliant per the listing, so it fits lead-free assembly flows without exemption paperwork.
