The ULN2803AD with Darlington Transistor Array Driver SOP-18 RoHS by HTC Korea is a reliable, cost-effective, and versatile circuit for driving an array of relays, motors, and other loads. Featuring an array of eight high-voltage/high-current Darlington transistors, this device is capable of driving up to 500mA per output at the peak collector-emitter voltage of 50V. With its wide operating voltage range of up to 50V, the ULN2803AD is ideal for any application requiring higher than normal voltage or current levels. Additionally, this versatile driver includes protection against thermal runaway, overvoltage, short circuits, and reverse voltage. This device is RoHS compliant and is available in an 18-pin SOP package.
