ULN2003APWRG4 Typical application Circuitry

ULN2003APWRG4

The ULN2003APWRG4 is a versatile Darlington transistor array chip designed for driving high-current loads with low-level logic signals. Applications needing the control of inductive loads, such as stepper motors, solenoids, and relays, frequently use it.

Application Scenarios: This chip is widely employed in automation systems, automotive applications, consumer electronics, and robotics for controlling relays, solenoids, stepper motors, and LED arrays.

Parameter Features: The ULN2003APWRG4 consists of seven Darlington pairs, each capable of sinking currents up to 500mA. It has a maximum voltage rating of 50V and includes built-in input resistors, making it compatible with both TTL and CMOS logic levels.

Circuit Design Example - Driving a Relay:

1. Input Connection: Connect the input of one of the Darlington pairs (e.g., pin 1) to a digital output pin of a microcontroller.

2. Output Connection: Connect the corresponding output (e.g., pin 16) to one terminal of the relay coil. The other terminal of the coil should be connected to the positive supply voltage.

3. Common Ground: Connect pin 8 of the ULN2003APWRG4 to the ground of the circuit to establish a common reference point for input and output voltages.

4. Power Supply: Ensure that the supply voltage for the relay coil is within the maximum voltage rating of the ULN2003APWRG4.

5. Flyback Diode: Place a diode across the relay coil terminals to protect the ULN2003APWRG4 from voltage spikes generated by the inductive load when the relay is deactivated.

Design Considerations:

- Current Rating: Check that the relay's current rating does not exceed the maximum current rating of the ULN2003APWRG4 to prevent damage.

- Input Voltage Levels: Verify that the input voltage from the microcontroller is within the acceptable range for the ULN2003APWRG4.

- Heat Dissipation: Consider heat dissipation requirements, as driving a relay can generate heat in the ULN2003APWRG4.

In this relay driving example, the ULN2003APWRG4's capability to interface low-level logic signals with high-power devices is highlighted. The detailed circuit design emphasizes the importance of managing heat, matching input voltage levels, and ensuring compatibility with the relay's specifications for the effective use of the ULN2003APWRG4 in driving relays.
