AL5802LP4

30V, ADJUSTABLE CURRENT SINK LINEAR LED DRIVER

Description

The AL5802LP4 combines 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

develops approximately 0.6V across the external resistor.

The AL5802LP4

’s open-collector output can operate from 0.8V to

30V making it suitable for industry standard 5V to 24V power

supplies without additional components.

PWM dimming of the LED current can be achieved by either driving

the BIAS Pin (4) with a low impedance voltage source, or driving the

EN Pin (6) with an external open-collector NPN transistor or

open-drain N-Channel MOSFET.

The AL5802LP4 is available in a X2-DFN1310-6 package and is

ideal for driving up to 120mA current.
