AL5801 Datasheet Adjustable Current Sink Linear Led Driver

Manufacturer: Diodes Incorporated

Overview: AL5801 100V, ADJUSTABLE CURRENT SINK LINEAR LED DRIVER.

General Description

The AL5801 bines a 100V N-channel MOSFET with a prebiased NPN transistor to make a simple, small footprint LED driver.

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

The internal pre-biased transistor develops approximately 0.56V across the external resistor.

Key Features

  • Feedback pin reference voltage VRSET = 0.56V at +25ºC -40 to +125ºC temperature range 1.1V to 100V open-drain output Negative temperature VRSET co-efficient automatically reduces the LED current at high temperatures Lead-Free Finish; RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Low thermal impedance SOT26 package with copper lead frame.
