ADVANACDEVDAINNCFEO IRNMNFAEOTIRWOMPNARTOIDOUNCT 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...
