Overview

The TLF35584QKVS1 is a multi-output System-Basis Chip (SBC) designed to power high-performance automotive microcontrollers like the Infineon AURIX family. It integrates a serial step-up/step-down pre-regulator with a 5V/600mA low-drop post-regulator, specifically engineered for applications requiring ISO 26262 ASIL-D compliance.

Why Choose This Part

This PMIC features a dedicated safety block with independent voltage monitoring and a configurable functional watchdog to ensure system integrity. It supports a wide input voltage range of 3V to 40V and includes two integrated trackers for precise sensor supply following the 1% accurate 5V reference.

Applications

Automotive ECU Power
Primary power supply for engine management, transmission control, and braking systems requiring functional safety.
ADAS Sensor Fusion
Powers radar and camera processing units where high efficiency and voltage monitoring are critical.
Electric Vehicle Inverters
Provides regulated supply and safety monitoring for traction inverter control boards.
Industrial Safety Controllers
Applicable in industrial automation systems that must meet high SIL (Safety Integrity Level) standards.
