Product Brief
INFINEON 2nd generation SPI Power Controller family (so called SPOC)
consists of a family of 5- or 6-channel integrated high-side switches suitable for
driving rear and central lighting loads into a body control module (BCM).
The complexity and density of BCMs is constantly increasing with more loads
and features inside the module, and car manufacturers are looking for modular
BCM concepts, allowing them to use the same platform, with various options, for
multiple car models, with or without LED option, for example.
The SPOC II family, scaled by number of channels and features (basic, LED mode,
cranking), addresses this trend and integrates multiple channels inside one
package to reduce board space. SPOC II devices feature a serial peripheral interface
(SPI), enabling customers to save I/Os in the microcontroller and reduce the
amount of external components required for a discrete implementation. The LED
mode in BTS5672E and BTS5682E is programmable via SPI.
