TLF35584QVHS2XUMA1

The TLF35584QVHS2XUMA1 is a highly efficient functional safety Power Management Integrated Circuit (PMIC) within the OPTIREG™ family. It is designed as a system-supply for safety-relevant automotive applications, particularly as a companion power IC for Aurix™ microcontrollers. The device features a buck-boost pre-regulator capable of operating across a wide 3V to 40V input range, ensuring stable operation during cold cranking and start-stop conditions. It provides multiple output rails including a 3.3V microcontroller supply, a 5.0V communication supply, and a precise 5.0V ADC reference. Integrated safety features include window and functional watchdogs, UV/OV monitoring, a safe state controller with secondary safety paths, and a built-in self-test (BIST) to meet ISO 26262 ASIL-D requirements.
