Multichannel SPI High-Side Power Controller | SPOC™ +2
High-Side Switch with diagnosis and embedded protection function for Automotive applications suitable for resistive, inductive and capacitive loads to replace electromechanical relays, fuses and discrete circuits. Capable to drive high inrush current loads such as lamps, HIDs or LED modules.
Protection Features: Absolute and dynamic temperature limitation with controlled restart, Over Current protection (tripping) with Programmable Restart Control and Current Threshold, Under Voltage shutdown, Over Voltage Protection with external components
Diagnostic Features: Proportional load current sense, Open Load in ON and OFF state, Short circuit to ground and battery, diagnosis feedback via SPI
Functional Safety Features: Limp Home Mode, Monitoring of Input pin status (IN and LHI), Checksum verification of Control Registers, Current Sense verification mode.
System Benefits vs. Discrete solution
PCB Area Savings: 4-6 channel device with smallest package size & highest integrated feature set
Scalable Solution: same pinout as previous generation SPOC™+, family pin-out and footprint concept to support population variants
Load Driving Capability: Up to 14A nominal load current with parallel channel configuration. Best in class power dissipation to support most severe usage conditions, ReverSave™,-50% compared to PRO+ & -12% vs. PRO+2
Feature to Cost: I/O savings due to SPI, optimized feature set for PWMoverSPI, best in class kILIS, less external components required due to integrated kILIS range switch and simple GND network, functional safety features, cranking, external drive, channel parallelization, configurable slew rate, configurable overload threshold and programmable restart control, logic supply is 3.3V compatible.
