ULN2003apg

ULN2003  dual-row 16-pin packaged transistor array drive circuit, maximum drive voltage=50V, current=500mA, input voltage=5V, suitable for TTL COMS circuit, the drive circuit is composed of Darlington tubes. It is a monolithic bipolar high-power, high-speed, high-voltage, and high-current Darlington transistor array chip. It is internally composed of 7 groups of Darlington transistor arrays, corresponding resistor networks and clamping transistor networks, and has the ability to drive 7 groups of loads at the same time.

ULN2003APG is used for driving circuit/transistor array.

ULN2003apg Characteristic description

belongs to the high withstand voltage, high current Darlington tube IC, ULN2003APG and ULN2003 are the same series of products. High withstand voltage, high current Darlington display, composed of seven silicon NPN Darlington tubes, the characteristics of this circuit are as follows:

Each pair of Darlingtons in ULN2003 is connected in series with a 2.7K base resistor. It can be directly connected to TTL and CMOS circuits under a working voltage of 5V, and can directly process data that originally required standard logic buffers to process.

ULN2003 has a high working voltage and large working current. The sink current can reach 500mA, and it can withstand a voltage of 50V when it is off. The output can also run in parallel with high load current. ULN2003 also integrates a diode to eliminate coil back EMF, which can be used to drive relays.

ULN2003APG, ULN2003APG transistor

It is a dual-row 16-pin package, NPN transistor matrix, maximum driving voltage=50V, current=500mA, input voltage=5V, suitable for TTL COMS, and a driving circuit composed of Darlington tubes. ULN is an integrated Darlington tube IC, which also integrates a diode that eliminates the coil back electromotive force. Its output end allows a current of 200mA, a saturation voltage drop VCE of about 1V, and a withstand voltage BVCEO of about 36V.

The external load of the user output port can be estimated based on the above parameters. Open-collector output is adopted, and the output current is large. Therefore, it can directly drive relays or solid state relays, and can also directly drive low-voltage bulbs. Generally, when the MCU drives ULN2003, it is more appropriate to pull up 2K resistance. At the same time, the COM pin should be left floating or connected to the power supply.
