AL5802 Datasheet Current Sink Led Driver

Manufacturer: Diodes Incorporated

Overview: AL5802 LINEAR MODE CURRENT SINK LED DRIVER.

General Description

The AL5802 bines a high gain NPN transistor with a pre-biased NPN transistor to make a simple small footprint LED driver.

The LED current is set by an external resistor connected from REXT pin (6) to GND pin (4).

The internal high gain transistor develops approximately 0.6V across the external resistor.

Key Features

  • Reference voltage VRSET = 0.65V.
  • -40 to +125°C temperature range.
  • 0.8V to 30V open-collector output.
  • Negative temperature co-efficient automatically reduces the LED current at high temperatures.
  • Low thermal impedance SOT26 with copper lead-frame.
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2).
  • Halogen- and Antimony-Free. “Green” Device (Note 3).
  • For automotive.
