What the 4.5 A peak output means for gate drive
The ADUM7223ACCZ-RL7 is a 2-channel isolated gate driver from the iCoupler family, built with magnetic coupling technology for galvanic isolation. Its 4.5 A peak output current is the headline spec: that drive strength directly determines how fast a power MOSFET or IGBT gate charges, which sets switching losses and dv/dt in a half-bridge or full-bridge topology. The 12 ns typical rise and fall time means the gate transitions cleanly without excessive Miller plateau dwell time, important when driving large-die IGBTs or paralleled MOSFETs.
Isolation and transient immunity for noisy environments
Rated at 2500 Vrms isolation, this part provides reinforced-level galvanic isolation for motor drives, industrial inverters, and switch-mode power supplies where the high-side gate driver must float above the DC bus. The 50 kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters when the switching node slews at tens of kilovolts per microsecond — without it, the isolator can latch or corrupt the gate signal. That CMTI rating puts the ADUM7223ACCZ-RL7 in the tier suited for fast-switching SiC and GaN half-bridges where dv/dt exceeds 30 kV/µs.
Propagation delay and dead-time budgeting
Maximum propagation delay of 68 ns (both directions) is a tight, symmetrical number that simplifies dead-time calculation in complementary switching stages. Channel-to-channel matching is implicit in the same-die construction of the iCoupler, which avoids the skew you get from two separate optocouplers. The 4.5 V to 18 V output supply range lets the driver interface directly with standard gate-drive bias rails for both logic-level and standard MOSFETs.
Package and board integration
Housed in a 13-VFLGA (5x5 mm) surface-mount package, the 13-LGA footprint keeps the layout compact for multi-channel designs.
Lifecycle and compliance
ROHS3 compliant per the listing, so it passes the current EU RoHS exemption roll-off.
