Description
The ULQ2001, ULQ2003 and ULQ2004 are high
voltage, high current Darlington arrays each
containing seven open collector Darlington pairs
with common emitters. Each channel rated at 500
mA and can withstand peak currents of 600 mA.
Suppression diodes are included for inductive
load driving and the inputs are pinned opposite
the outputs to simplify board layout. The versions
interface to all common logic families. These
versatile devices are useful for driving a wide
range of loads including solenoids, relays DC

motors, LED displays filament lamps, thermal
print-heads and high power buffers. The
ULQ2001A/2003A and 2004A are supplied in 16
pin plastic DIP packages with a copper leadframe to reduce thermal resistance. They are
available also in small outline package (SO16) as
ULQ2003D1/2004D1. The ULQ2003 is available
as Automotive Grade in SO16 package. The
commercial part numbers is shown in the order
codes. This device is qualified according to the
specification AEC-Q100 of the Automotive
market, in the temperature range -40 °C to 125 °C
and the statistical tests PAT, SYL, SBL are
performed.
