Overview
2544 QUAD DARLINGTON POWER DRIVER Combining logic gates and high-current bipolar outputs, the UDN2544B quad Darlington power driver provides an interface between low-level logic circuitry and high-power loads.
Each of the four outputs can sink up to 1.
8 A in the on state with peak inrush currents to 2.
5 A.
The four power outputs are each comprised of an opencollector Darlington driver and an internal flyback/clamp diode for switching inductive loads.
They feature a minimum breakdown and sustaining voltage of 50 V.
The logic inputs are compatible with TTL and 5 V CMOS logic systems.
This device is particularly well-suited for unipolar stepper motor drive applications.
With complementary control inputs and an activelow ENABLE, the UDN2544B makes it easy to implement full stepping of a stepper motor with only two microcontroller/microprocessor control lines.
Other typical applications include relay or solenoid driving and incandescent or LED lamp driving.
The UDN2544B is supplied in a 16...
