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.
Pin Assignments
The LED current is set by an external resistor connected from
REXT Pin (2) to GND Pin (1). The internal high-gain transistor
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.
