ULN2002D

A new three-channel relay driver circuit that

Pin Arrangement

Description

ULN2002D is a monolithic integrated high voltage

withstand, high current Darlington array IC, with

five independent Darlington drive channels inside

the circuit. A freewheeling diode is designed inside

the circuit, which can be used to drive inductive

loads such as relays and stepping motors. Single

Darlington

The tube collector can output 500 mA current, and

multiple channels can be connected in parallel to

achieve higher current output capacity. The circuit

can be widely used in relay drive, lighting drive,

display screen drive (LED), stepping motor drive

and logic buffer.

COM

Each Darlington tube of ULN2002D is connected in

series with a 2.7K base resistance, which can be

directly connected to the TTL/CMOS circuit under

5V working voltage, and can directly process the

data that originally needed standard logic buffer to

process.

Each Darlington tube input stage of ULN2002D

is designed with a 4K pull-down resistance to

ground, which can prevent the load

misoperation caused by the uncertain state of

the MCU.
