The integrated high-efficiency buck-boost pre-regulator operates over a wide input voltage range of 3 V to 40 V, ensuring stable system supply even during severe automotive cranking and start-stop scenarios without interruption. A dedicated precision reference-regulator supplies the microcontroller's ADC independent of load steps to guarantee measurement accuracy, while independent voltage trackers act as protected sources for off-board sensors, offering robust short-to-battery protection. The flexible state machine, featuring an ultra-low quiescent current standby mode and a cyclic wake-up timer, favors energy-efficient usage in a broad range of automotive applications. Comprehensive safety features, including a configurable monitoring unit, functional and window watchdogs, and a safe state controller, enable easy realization of ASIL D systems according to ISO 26262. The OPTIREG™️ PMIC TLF4D985QKV03 comes in a thermally enhanced PG-LQFP-64 package capable of automated optical inspection. Fully AEC-Q100 qualified, this device is a robust, safe, and reliable supply companion for Infineon AURIX™️ TC2x and TC3x microcontrollers, ensuring the highest safety standards at the system level for mission-critical applications.
