Combining AND logic gates and inverting high-current bipolar
outputs, the UDN2540B and A2540SLB quad Darlington power drivers
provide interface between low-level signal-processing circuits and
power loads totaling 360 W. Each of the four independent 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
leads. They feature a minimum breakdown and sustaining voltage of
50 V. The logic inputs are compatible with TTL and 5 V CMOS logic
systems.
Typical applications include print heads, relays, solenoids, and
dc stepping motors. These drivers can also be used to drive high-
current incandescent lamps, LEDS, and heaters. A similar device,
specifically intended for driving a unipolar stepper motor in the
two-phase drive format, is the UDN2544B.
The UDN2540B is supplied in a 16-pin batwing power DIP; the
A2540SLB is supplied in a 20-lead batwing power SOIC for surface-
mount applications. The batwing construction provides for maximum
package power dissipation in a standard construction. At 25°C, and
with only 1 sq. in. of copper foil at the ground tabs, either package is
capable of safely dissipating more than 2 W.
