TLF35584QVVS2 The TLF35584QVVS2 is a multiple output system supply for safety-relevant applications supplying 3.3V-μC, transceivers, and sensors.
The wide switching frequency range optimizes efficiency and filter components, while a dedicated reference-regulator supplies the ADC independently and tracks the two sensor-supplies. The TLF35584 is available in a small, thermally enhanced VQFN-48 (QV-version) suitable for automated optical inspection

- The device is PRO-SIL™ ISO26262-compliant and fulfils the properties required by the ISO26262 (Automotive Safety) Standard (for more info visit www.infineon.com/PRO-SIL).
Required safety integrity functions to reach ASIL-D efficiently on system level are already implemented: UV/OV-monitoring of all rails with independent reference, detecting dependent failures by flexible watchdog-concept, monitoring of μC’s safety management unit, and a safe state controller providing secondary safety paths. A built-in self-test is ensuring the proper function of the relevant safety features. All features are perfectly aligned to the Infineon’s AURIX™-requirements, but are extended to support other μCs as well. All safety-relevant configurations are protected and can only be changed by special, successfully performed unlock/lock-sequence.
Furthermore PRO-SIL™ ISO26262-compliant product development follows a product specific safety plan defined by Infineon. The product development follows the Infineon V – model based development lifecycle which encompasses all ISO26262 required activities and work products related to the product scope. Product relevant safety requirements and required metrics are captured and verified through the development of the product, this includes the product safety concept and ultimately a product safety case which provides the argumentation and evidence showing achievement of the defined safety requirements and process compliance, including all essential supporting processes.
An independent functional safety management organization supports the ISO26262 conform safety lifecycle. For ISO26262-compliant products a Safety Manual and a Safety Analysis Summary Report are available* in addition to Infineon standard documentation.
Moreover Infineon offers expert support for system integrators to achieve the required ASIL on system level. Infineon’s activities result in a simplified integration in safety-related applications.
