Overview

The TLF35584QKVS2 is a high-efficiency automotive PMIC designed to support safety-critical applications with a serial step-up and step-down pre-regulator architecture. It is ISO 26262 compliant up to ASIL-D, featuring integrated functional watchdog timers and independent voltage monitoring blocks for robust system supervision.

Why Choose This Part

This PMIC offers a wide input voltage range of 3V to 40V, allowing it to maintain regulation during cranking or load dump conditions. Its primary advantage is the integrated PRO-SIL safety features, including a configurable window watchdog and safe-state control, which simplify the path to ASIL-D certification.

Applications

Electric Power Steering (EPS)
Provides stable 3.3V power and safety monitoring for high-integrity steering actuators.
Battery Management Systems (BMS)
Manages power rails and monitors system health in high-voltage EV battery controllers.
Domain Controllers
Acts as a primary power supply for automotive compute nodes requiring ASIL-D functional safety.
Inverter Control
Supplies regulated power to gate driver logic and MCUs in traction inverter systems.
