Summary of Features:

• 8-bit serial peripheral interface (daisy chain capable SPI) for control and diagnosis.
• PWM driving possible through direct inputs or via SPI
• Integrated control for one external smart power switch  Selectable AND-/ OR- combination for the parallel inputs (PWM control)
• Load type configuration via SPI (bulb or LEDs)
• Very low Stand By current
• Fail Safe activation via Limp Home pin and  configuration via input pins only
• Green Product (RoHS-Compliant)
• AEC Qualified.

Benefits:

• Full modularity of the SPOC+ Family enables development re-use and quick adaptation to loadlist changes
• Extra small leadless package (TSON24) helps reduce the PCB area
• Simplified overal PCB layout, small PCB area, reduced bill of material on system level
• Control of one external PROFETs through SPI gives the flexibility to use scalable, pin compatible devices to drive optional loads
• Smaller MCU package required as control is done via SPI daisy chains
• Added diagnostics via SPI in addition to multiplexed current sense
• Module quality improvement using a pre-tested "system on chip" device and simplified design

Target Applications:

• Highside power switch for 12 V grounded loads
• Especially designed for standard exterior lighting like high beam, low beam, indicator, parking light, using bulbs, HIDL or LEDs
• Further automotive and industrial applications such as heating, motor driving, energy and power distribution
• Replaces electromechanical relays with fuses, as well as discrete chip sets
