QUAD DARLINGTON

POWER DRIVER

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.

OUT

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.
