AL5802LP-7

AL5802LP ADVANCE INFORMATION NEW PRODUCT LED DRIVER, 30V, LINEAR, ADJUSTABLE, CURRENT SINK Description Pin Assignments The AL5802LP combines a high-gain NPN transistor with a prebiased NPN transistor to make a simple, small footprint LED driver. 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. Internal Schematic (Top View) (Bottom View) The AL5802LP is available in a U-DFN1616-6 (Type F) package and is ideal for driving 10mA to 120mA LED currents.
