AL5801 - ADJUSTABLE CURRENT SINK LINEAR LED DRIVER
The AL5801 combines a 100V N-channel MOSFET with a prebiased NPN transistor to make a simple, small footprint LED driver.
The LED current is set by an external resistor connected from REXT pin (4) to GND pin (6).
The internal pre-biased transistor develops approximately 0.56V across the external res
