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 and UCC27624V. Some of the benefits are discussed below:
Power Density: The UCC276x4 family 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.
Robustness: The UCC276x4 family has a 30V max VDD and the –10V negative voltage handling enables excellent noise and transient handling without the need for external components such as clamp diodes on the inputs and outputs.
Flexibility: The UCC276x4 family of devices come in a multitude of common industry packages to fit design engineers' preferences and requirements. Package differences include thermal package options or even leadless options.
