AL5802LP
LED DRIVER, 30V, LINEAR, ADJUSTABLE, CURRENT SINK
Description
The AL5802LP combines a high-gain NPN transistor with a pre-
biased NPN transistor to make a simple, small footprint LED driver.
Pin Assignments
The LED current is set by an external resistor connected from REXT
pin (2) to GND pin (3), and the internal high-gain transistor develops
approximately 0.6V across the external resistor.
The AL5802LP’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 (6) with a low impedance voltage source, or driving the
EN pin (4) with an external open-collector NPN transistor or
open-drain N-Channel MOSFET.
The AL5802LP is available in a U-DFN1616-6 (Type F) package and
is ideal for driving 10mA to 120mA LED currents.
