ULN2003 NPN Darlington IC

Features:-

• Seven Darlington arrays
• Output current 500ma per driver (600mA peak)
• Output voltage 50v integrated suppression diodes
• Inductive loads outputs can be paralleled
• Higher current .TTL/CMOS/PMOS/DTL compatible inputs inputs pinned opposite outputs to simplify layout.
• Maximum Output Voltage:50V
• Maximum Input Voltage:30V
• Storage Temperature Range:-55 to 150°C
• The most easy module to learn how to control the Stepper and finish the simple project.
• The logic control voltage:3~5.5V
• Motor Supply Voltage: 5~ 15V
• It can sink 500mA from a 50V supply, but you’d better limit the driver voltage under 15v.
• Operating temperature: -25 degree Celsius ~ +90 degree Celsius 500 mA rated collector current (single output)
• 50 V output (there is a version that supports 100 V output)
• Includes output flyback diode

Darlington Transistor: What is it? (Darlington Pair)

Darlington transistor (also known as a Darlington pair) is an electronics component made via the combination of two BJTs (Bipolar Junction Transistor) connected in such a way that it allows a very high amount of current gain. This is achieved through a compounding amplification, whereby the current is amplified by the first transistor and then further amplified by the second transistor. As this compound structure is designed from two BJTs, this transistor is also known as “Darlington Pair”. This transistor behaves as a single unit transistor as it has only one emitter, collector, and base. The Darlington transistor was invented by Sidney Darlington in 1953.
