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 (2) to GND pin (3), and the internal high-gain transistor develops

approximately 0.6V across the external resistor.

The AL5802

LP’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.
