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 Table 1 (order codes). This device is qualified according to the specification AEC-Q100 of the Automotive market, in the temperature range -40 to 125 , and the statistical tests PAT, SYL, SBL are performed.
