AL5802, CURRENT SINK LED DRIVER
The AL5802 combines a high gain NPN transistor with a pre-biased NPN transistor to make a simple small footprint LED driver.
The LED current is set by an external resistor connected from REXT pin (6) to GND pin (4).
The internal high gain transistor develops approximately 0.6V across the external re
AL5802 Features
* Reference voltage VRSET = 0.65V
* -40 to +125°C temperature range
* 0.8V to 30V open-collector output
* Negative temperature co-efficient automatically reduces the LED current at high temperatures
