QUAD POWER DRIVER

Providing interface between low-level logic and power loads to

100 W, the UDx2543B and UDx2543EB quad power drivers combine

AND logic gates and high-current bipolar outputs. Each of the four

independent outputs can sink up to 700 mA in the ON state. The

outputs have a minimum breakdown voltage (load dump) of 60 V and

a sustaining voltage of 35 V. The inputs are compatible with most

TTL, DTL, LSTTL, and 5 V CMOS and PMOS logic systems.

Over-current protection has been designed into each channel of

the UDx2543B/EB and typically occurs at 1 A. It protects any one

channel from output short circuits with supply voltages up to 25 V.

When the maximum output current is reached, that output stage is

driven linearly. If the over-current condition continues, that output’s

thermal limiting will operate, limiting that output’s power dissipation to

approximately 2.4 W. The outputs also include diodes for voltage

clamping with inductive loads such as relays, solenoids, or dc stepper

motors.

These devices are supplied in a 16-pin power DIP of batwing

construction (suffix ‘B’) to provide for maximum package power dissi-

pation. They are also available in a 28-lead PLCC (suffix ‘EB’) for

surface-mount applications. All devices are rated for continuous

operation over the temperature range of -20°C to +85°C (UDN2543B/

EB) or for use in automotive applications over an extended tempera-

ture range as the UDQ2543B/EB.
