SPOC™: SPI Power Controller
SPOC™ devices are high-side smart power Multichannel
switches providing embedded protection diagnosis and
intelligence. They are specially designed for standard
exterior lighting in automotive applications, but can be
used for further automotive and industrial applications
such as heating, motor driving or power distribution.
Integration helps reducing the complexity of the
lectronics, allowing board space reduction and
decreasing the need for external components. Control,
configuration and diagnosis are carried out via a Serial
Peripheral Interface (SPI), which saves I/Os on the
microcontroller and provides flexibility for the solution.
Furthermore, Fail Safe modes are supported, which
enhances safety in operation.
Re-use and design flexibility is supported through the pin,
function and package compatibility of the devices within
each SPOC™ family.
SPOC™ provides decisive advantages on system level and
for a wide range of applications.
