Product details

The ADUM4221CRIZ from Analog Devices is an isolated half-bridge gate driver designed for IGBTs, delivering 4 A source and 6 A sink peak output current from a 2.5 V to 6.5 V supply rail. The wide-body 16-SOIC package (7.50 mm width) provides the creepage distance needed for reinforced isolation in motor drives, uninterruptible power supplies, solar inverters, and industrial power converters operating from -40°C to 125°C junction temperature.

Peak output current — sizing the gate drive

The 4 A source / 6 A sink peak rating determines how fast the IGBT gate capacitance charges and discharges. A higher sink current than source is common for IGBTs to pull the gate low quickly during turn-off, reducing switching losses and cross-conduction risk.

Package and isolation considerations

The 16-SOIC wide-body (7.50 mm width) is a surface-mount package. The wide creepage distance between input and output sides is essential for meeting isolation standards in motor-drive and inverter designs.

For new designs, this part is a current-production choice with no imminent obsolescence risk.

Frequently asked questions

What is the closest alternative to ADUM4221CRIZ?

Within the same ADUM4221 family, the ADUM4221ARIZ-RL is functionally identical — same gate type (IGBT), same half-bridge configuration, same 4 A / 6 A peak output, same 25 ns / 30 ns rise/fall times. The difference is packaging: the ARIZ-RL variant ships in Tape & Reel (and Cut Tape / Digi-Reel) rather than Tube. For a reel-fed production line, the ARIZ-RL is the direct drop-in; for prototype or low-volume builds, the CRIZ in Tube is fine. Outside the ADUM4221 family, the LTC4442EMS8E#PBF and LTC4442IMS8E#PBF are N-channel MOSFET drivers with faster switching (12 ns rise, 8 ns fall) but lower

Does ADUM4221CRIZ have built-in dead-time?

The ADUM4221 family includes a dead-time control feature that prevents shoot-through by inserting a programmable delay between the high-side and low-side switching transitions. The exact dead-time range and programming method are detailed in the datasheet; the part number suffix (CRIZ) indicates a specific dead-time setting variant within the family.
