Diodes Incorporated AL5802LP
The AL5802LP combines a high-gain NPN transistor with a prebiased NPN transistor to make a simple, small footprint LED driver. 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. The AL5802LP is available in a U-DFN1616-6 (Type F) package and is ideal for driving 10mA to 120mA LED currents.| Part No. | AL5802LP |

DESCRIPTION
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. 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.FEATURES
