Description

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.  UDN2540B and A2540SLB  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 highcurrent incandescent lamps, LEDS, and heaters.  UDN2540B and A2540SLB  specifically intended for driving a unipolar stepper motor in the two-phase drive format.

The  UDN2540B and A2540SLB  is supplied in a 16-pin and 20-lead batwing power SOIC for surfacemount 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.
