ULN2001D

Description

ULN2001D is a single-chip integrated high voltage,

high current Darlington transistor array, which

contains three independent Darlington transistor

drive channels inside the circuit. The circuit is

internally designed with a freewheeling diode, which

can be used to drive inductive loads such as relay

stepper motors. A single Darlington tube collector

can output a current of 500mA, and connecting

multiple channels in parallel can achieve higher

current output capabilities. This circuit can be widely

used in relay drive, lighting drive, display screen

drive (LED), stepper motor drive, and logic buffer.

COM

Each Darlington transistor of ULN2001D is connected

in series with a 2.7K base resistor, which can be

directly connected to TTL/CMOS circuits at a working

voltage of 5V, and can directly process data that

originally required standard logic buffers.

In addition, each Darlington transistor input stage of

ULN2001D is designed with a 4K ground pull-down

resistor to prevent load misoperation caused by the

unstable state of the microcontroller.
