Product details

Peak current and switching speed for gate drive

The asymmetric sink capability provides faster turn-off, which reduces switching losses in hard-switched topologies like automotive DC-DC converters and motor-drive inverters.

Temperature range and package for under-hood use

The SOT-23-6 package occupies minimal board area, but designers should note the absence of an exposed thermal pad—thermal vias to a ground plane are recommended to keep the die temperature within limits under continuous high-current drive.

Frequently asked questions

Is UCC27531QDBVRQ1 AEC-Q100 qualified?

Yes, the part is listed under the Automotive, AEC-Q100 series, confirming it meets the stress and qualification requirements for automotive-grade applications.

What is the difference between UCC27531 and UCC27531QDBVRQ1?

The UCC27531QDBVRQ1 is the AEC-Q100-qualified automotive-grade variant of the base UCC27531. The 'Q1' suffix denotes automotive qualification, and the 'DBVR' suffix specifies the SOT-23-6 package in Tape & Reel. The base UCC27531 may not carry the same automotive reliability screening.
