Description

The AL5801 combines a 100V N-channel MOSFET with a prebiased NPN transistor to make a simple, small footprint °C driver. The °C 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 resistor. The AL5801 open-drain output can operate from 1.1V to 100V enabling it to operate 5V to 100V power supplies without additional components. PWM dimming of the °C current can be achieved by driving the BIAS pin (1) with an external, open-collector NPN transistor or open-drain N-channel MOSFET. The AL5801 is available in a SOT26 package and is ideal for driving °C currents up to 350mA. Features Feedback pin reference voltage VRSET = 0.56V at +25°C -40 to +125°C temperature range 1.1V to 100V open-drain output Negative temperature VRSET co-efficient automatically reduces the °C current at high temperatures Lead-Free Finish; RoHS Compliant Halogen and Antimony Free. “Green” Device Low thermal impedance SOT26 package with copper lead frame
