AL5802LPL-7

Overview

The AL5802LPL-7 is a linear LED driver IC manufactured by Diodes Incorporated, designed for simple and compact lighting applications. It integrates a high-gain NPN transistor with a pre-biased NPN transistor to form a small-footprint current sink. The device features an open-collector output capable of operating within a voltage range of 0.8V to 30V, allowing compatibility with 5V to 24V power supplies without additional components. Key electrical specifications include a maximum supply voltage of 30V, an output current capability of 150mA, and a power dissipation rating of 500mW. It operates across a temperature range of -40°C to +150°C and is housed in a DFN-1616-6 surface-mount package.
