Diodes Incorporated AL5802LP4
The AL5802LP4 combines a high-gain NPN transistor with a pre-biased NPN transistor to make a simple small footprint LED driver. 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.| Part No. | AL5802LP4 |

DESCRIPTION
Pin Assignments The LED current is set by an external resistor connected from REXT Pin (2) to GND Pin (1). 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.FEATURES
