Product Overview
ADUM3224WBRZ is an automotive-oriented isolated precision half-bridge gate driver from Analog Devices. It provides independent high- and low-side outputs with 4 A peak drive, up to 1 MHz switching and a B-grade secondary UVLO threshold near 6.9 V.
The W model is backed by automotive qualification/reliability documentation and should be treated as a distinct orderable from commercial ADuM3223 variants. That matters where component qualification records, manufacturing controls or automotive reliability evidence are part of the sourcing requirement.
Technical Specifications
| Parameter | Confirmed Information |
|---|---|
| Peak output current | 4 A |
| Maximum switching frequency | 1 MHz |
| Input logic | 3.3 V / 5 V CMOS compatible |
| Output-side supply | 4.5 V to 18 V |
| Secondary UVLO | Approximately 6.9 V |
| Maximum propagation delay | 59 ns |
| Maximum channel matching | 5 ns |
| Common-mode transient immunity | >25 kV/µs |
Automotive and Gate-Drive Considerations
The W orderable should be retained when the approved design depends on the associated automotive qualification and controlled manufacturing evidence. A commercial half-bridge driver with similar electrical numbers is not automatically equivalent from a qualification standpoint.
The approximately 6.9 V UVLO still needs to be matched to the external transistor’s required gate voltage and the minimum isolated bias rail under transient conditions.
