Summary of Features:

• 16 bit serial peripheral interface for control and diagnosis Integrated PWM generator
• Integrated control for two external smart power switches
• LED/Bulb modes available for channels 2 and 3 to adapt the switching and diagnosis behavior
• Very low stand-by current
• Enhanced electromagnetic compatibility (EMC) for bulbs as well as LEDs with increased slew rate
• Stable behavior at under voltage
• Device ground independent from load ground
• Green Product (RoHS-Compliant)
• AEC Qualified

Benefits:

• Very low power dissipation relaxes the PCB design and enables usage of a standard plastic housing
• Internal PWM generation enables full PWM capability of all loads while unloading the MCU and SPI traffic
• Control of two external PROFETs through SPI gives the flexibility to use scalable, pin compatible devices to drive optional loads
• Simplified overal PCB layout, small PCB area, reduced bill of material on system level
• 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 pretested "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
