Product details

It delivers 4A peak output current per channel, enough to drive medium-power IGBTs and MOSFETs in motor drives, solar inverters, and switch-mode power supplies. The 5700Vrms isolation rating and 150kV/µs common-mode transient immunity (CMTI) let it sit across the isolation barrier in noisy industrial environments without false triggering. The output supply range spans 4.5V to 35V, which means the same part can drive a 12V logic-level MOSFET or a 24V IGBT gate. Propagation delay is 33ns (rising) and 44ns (falling) maximum, with pulse-width distortion held to 16ns — tight enough for high-frequency switching stages where dead-time margin is tight.

Temperature grade and approvals

Approvals include CQC, CSA, UL, and VDE — the certifications a panel builder needs for CE-marked equipment.

Frequently asked questions

What is the output current of ADUM4221-2CRIZ-RL?

The ADUM4221-2CRIZ-RL delivers 4A peak output current per channel. That's the peak gate-drive capability for driving IGBTs or power MOSFETs.

Can ADUM4221-2CRIZ-RL replace ADUM4221-2BRIZ?

The ADUM4221-2CRIZ-RL is the Tape & Reel variant of the ADUM4221-2CRIZ (which is the Tube variant). The -2BRIZ suffix would need to be checked against ADI's ordering guide for package and temperature range differences. The core isolation and drive specs (5700Vrms, 4A peak) are shared across the ADUM4221 family.
