Infineon Technologies AG Power - Power Supply ICs - OPTIREG™ PMIC - TLE9243QK TLE9243QK

The TLE9243QK is an application specific multiple output system supply for transmission applications supplying 5 V-μC, transceivers, and sensors by an efficient and flexible pre-/post-regulator concept over a wide input voltage range. Like other Application Specific PMICs, TLE9243QK is a power management IC that levers system cost optimization potential and FuSa harmonization for a specific application. The TLE9243QK offers the complete power supply functionality as well as application specific features for transmission systems. Beside the power supply functions, the TLE9243QK provides sensor interfaces for three channels including one 9V LDO per channel as well as three channels to drive external n-channel power switches. The TLE9243QK has been developed according to ISO 26262 targeting systems up to ASIL-D. Multiple safety features as window and functional watchdog and monitoring functions enable easy realization of ASIL-D together with the Infineon’s AURIX™ family and other microcontrollers as well. The TLE9243QK is coming in a Grade 0 thermally enhanced LQFP-64 suitable for harsh environments. For datasheet and further support, please contact your sales representative.

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™ ISO 26262-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 ISO 26262 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 ISO 26262 conform safety lifecycle. For ISO 26262-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. *NDA required Access to complete OPTIREG™ PMIC technical documentation including data sheets, app notes, etc.: To get access to the full technical documentation you need access to the MyInfineon Collaboration Portal Please register* under myinfineon.com with your company e-mail address and with this, request access to the MyInfineon Collaboration Portal.
