AL5802LP
LED DRIVER, 30V, LINEAR, ADJUSTABLE, CURRENT SINK
Description
The AL5802LP combines a high-gain
NPN transistor with a prebiased
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 (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 impedan...
