Product Introduction

Overview

The ALED6001TR, produced by STMicroelectronics, is an automotive-grade (AECQ100 compliant) LED driver designed to drive one string of high-brightness LEDs. It combines a boost controller and high-side current sensing circuitry, making it suitable for various topologies such as boost, SEPIC, and floating load buck-boost. The device supports PWM dimming through an external MOSFET and offers high precision current sensing with ±4% accuracy over the entire temperature range and production spread. It also includes several protection features, including thermal shutdown, output overvoltage protection, and LED overcurrent protection.
