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 dissi­pation. 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 tempera­ture range as the UDQ2543B/EB.

FEATURES

■ 700 mA Output Current per Channel

■ Low Output-Saturation Voltage

■ Integral Output Transient-Suppression Diodes

■ TTL, CMOS, PMOS, NMOS Compatible Inputs

■ Independent Over-Current Protection for Each Output

NOTE: These devices do not include an absolute thermal shutdown. Package power dissipation under fault conditions (2.4 W in the faulted

channel) must therefore be evaluated at maximum operating temperature.

Negative current is defined as coming out of (sourcing) the specified terminal.
As used here, -100 is defined as greater than +10 (absolute magnitude convention) and the minimum is implicitly zero.
* Pulse test, allowable package power dissipation will be exceeded at increased ambient temperatures.
† All inputs simultaneously, all other tests are performed with each input tested separately.
