The UCC276X4 devices are a family of high-current, low-side drivers designed primarily to drive MOSFETs and IGBTs in both automotive and industrial applications. The family includes both the single channel UCC27614 and dual channel UCC27624.

Power Dense: The UCC276x4 features high drive current, up to 10A, to reduce switching losses and improve overall system efficiency. This combined with the small SON package options for both the dual and single channel versions makes the UCC276x4 family one of the most power dense gate drivers available.

Robust: The UCC276x4s 30V max VDD and the -10V negative voltage handling enable excellent noise and transient handling without the need for external components such as clamp diodes on the inputs and outputs.

Target End Equipments

The UCC276X4 can be utilized in a wide variety of end equipments. Consider how the product features can improve a system design.
