Product details

5000 Vrms isolated gate driver with 2.3 A peak drive

The ADI ADUM4121BRIZ is a single-channel isolated gate driver from the iCoupler family, built around magnetic coupling technology. The output supply range of 7.5 V to 35 V covers standard gate drive voltages for silicon and wide-bandgap devices, and the 18 ns typical rise/fall time keeps switching losses contained at moderate frequencies.

Propagation delay and pulse-width distortion — timing budget for the bridge

Maximum propagation delay is 42 ns low-to-high and 53 ns high-to-low, with pulse-width distortion capped at 13 ns. That asymmetry matters when you are timing dead-band between the high-side and low-side switches in a half-bridge — a 13 ns skew eats into your margin directly. The 150 kV/µs CMTI ensures the output does not glitch when the switching node slews at tens of kV/µs, which is the real-world test for a gate driver in a hard-switched inverter.
