Diodes Incorporated AL5802LP-7
The AL5802LP combines a high gain NPN transistor with a prebiased NPN transistor to make a simple, small footprint LED driver. The AL5802LP open-collector output can operate from 0.8V to 30V enabling it to operate from 5V to 24V power supplies without additional components. The AL5802LP is available in a U-DFN1616 Type F package and is ideal for driving 10mA to 120mA LED currents.| Part No. | AL5802LP-7 |

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. Internal Schematic (Top View) (Bottom View) Package: U-DFN1616-6● The collector of Q2 is connected to pin 1 and pad 7 which is on the underside of the package
● Pad 8 is electrically tied to the collector of Q1 and to the base of Q2, i.e. it is common with terminal 4
FEATURES
● Reference Voltage VRSET = 0.65V● -40 to +125°C Operating Temperature Range
● 0.8V to 30V Open-Collector Output
● Negative Temperature Coefficient – Automatically reduces the LED current at high temperatures
● Low Thermal Impedance, Small Footprint DFN1616 Package with Exposed Pad...
