POWER DRIVER  
Combining logic gates and high-current bipolar outputs, the  
UDN2544B quad Darlington power driver provides an interface be-  
tween 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 open-  
collector 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 active-  
low 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-pin batwing power DIP. The  
batwing construction provides for maximum package power dissipation  
in a standard DIP construction. At 25°C, and with only 1 sq. in. of  
copper foil at the ground tabs, the package is capable of safely dissi-  
pating 3.8 W.
