AL5802LPL LED DRIVER, 30V, LINEAR, ADJUSTABLE, CURRENT SINK Description Pin Assignments The AL5802LPL 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 the 1 2 3 R Pin (4) to the GND Pin (6), and the internal high gain transistor EXT develops approximately 0.6V across the external resistor. 7 The AL5802LPLs open-collector output can operate from 0.8V to 30V making it suitable for industry standard 5V to 24V power supplies without additional components. 6 5 4 PWM dimming of the LED current can be achieved by either driving Internal Schematic (Bottom View) the BIAS Pin (1) with a low impedance voltage source, or driving the (Top View) EN Pin (5) with an external open-collector NPN transistor or open-drain N-Channel MOSFET. Package: U-DFN3030-6 (Type B) The Collector of Q2 is Connected to Pin 2 and Pad 7 which is on The AL5802LPL is available in a U-DFN3030-6 (Type B) package and the Underside of the Package is ideal for driving 10mA to 120mA LED currents.
