Product Summary

Providing improved output current limiting, the UDK2559BT quad power driver combines AND logic gates and high-current bipolar outputs with complete output protection. Each of the four outputs will sink 700 mA in the on state. The outputs have a minimum breakdown voltage (load dump) of 60 V and a sustaining voltage of 40 V. The inputs are compatible with TTL and 5 V CMOS logic systems. The device can be used to drive various loads including incandescent lamps (without warming or limiting resistors) or inductive loads such as relays, solenoids, or dc stepping motors.
