AL5802LPL-7

AL5802LPL LED DRIVER, 30V, LINEAR, ADJUSTABLE, CURRENT SINK Description Pin Assignments The AL5802LPL 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 the REXT Pin (4) to the GND Pin (6), and the internal high gain transistor 1 2 3 develops approximately 0.6V across the external resistor. 7 The AL5802LPL’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. 6 PWM dimming of the LED current can be achieved by either driving the BIAS Pin (1) with a low impedance voltage source, or driving the EN Pin (5) with an external open-collector NPN transistor or open-drain N-Channel MOSFET.
