Qualified for automotive and industrial applications, such as lighting, heating, motor Logic supply (5V) Input signal of channel x External driver output External driver diagnosis enable Multiplexed current sense output Limp home mode activation SPI signals Ground connection Power output of channel x Power supply (12V) OUT4 OUT3 OUT2 OUT1 External Driver Control SPI SI The SPOC+ family, scaled by number of channels and added features, addresses these trends by implementing smart high-side drivers together with added intelligence inside one package. Full scalability is provided through the footprint and software compatibility of all SPOC+ devices. Integration helps reducing the complexity of the electronics, 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 enhance safety in operation. For 12V grounded high-side loads 4 Channel 1 ESD Protection IS The complexity and density of electronic modules is constantly increasing as more and more loads and functions keep on being implemented. Car manufacturers , automotive suppliers and also industry players are looking for modular and scalable solutions to be able to adapt to a variety of options and re-use the developed electronics for further projects. At the same time, the modules need to be optimized in terms of size and weight.
