Bipolar Junction Transistor (BJT) Arrays, in general, are grouped assemblies of same transistors that serve as a single, large semiconductor device to the circuit. This is common when very small current and voltage requirements are needed in an IC application, with the end goal being a higher combination of current and voltage than can be offered by an individual transistor. One such example is the JAN2N2919U, a control and driver array staple used in many consumer applications.

Applications of JAN2N2919U

The JAN2N2919U is commonly used as a driver array in consumer electronics. It is suitable for low-frequency and low-power applications such as DC motors, numerically controlled relays, and direct logic logic control circuits. Moreover, it is also suitable for laser diode arrays, form current sources for analog and digital circuits, and for voltage follower applications.

Furthermore, it is also used in the telecommunications industry for PABX and computer switching applications, as well as for hardware level encoding and decoding operations. Finally, it is applicable in applications such as motor control, where it can provide pulse width modulation, voltage verification, and associated power conversion requirements.

Features of JAN2N2919U

The JAN2N2919U is designed to be used in 4-bit binary applications, thanks to its combination of high speed and low-voltage characteristics. In addition, the JAN2N2919U has a wide range of parameters, ranging from an operating current of 150mA to a maximum of 100mA. In comparison to standard BJT transistors, the JAN2N2919U provides a low-voltage drop of only 0.3V.

Other features of the JAN2N2919U include internal bias circuitry, which can be used to trim the speed and switch point of its output drivers, as well as its adjustable source current output. Several protective features are also built in, including thermal protection, reverse connection protection, under-voltage lockout, and current limiting.

Working Principle of JAN2N2919U

The JAN2N2919U is a 4-bit binary transistor array configured as an 8-bit word. Each bit consists of two BJT transistors: one P-type and one N-type. The P-type transistor prevents voltage from passing from its collector to its emitter until a certain amount of current passes through it. The N-type transistor serves as a transistor switch. When a certain amount of current passes through it, it will turn off, preventing voltage from passing from its collector to its emitter.

The current level of the transistors determines their “on” or “off” state. Each transistor acts as a basic switch to control and regulate the input signals to the application. The higher the current of the transistor, the higher the threshold voltage for it to turn off. The threshold voltage is inversely related to the resistance of the transistor. By changing the polarization of the transistor, the resistance seen by the input signal can be varied.

The transistors in the JAN2N2919U can be programmed to take any one of 256 binary states. This allows the JAN2N2919U to provide the user with precise control over its output. It can also be used to create an array of logic gates in order to create more complex control functions.

Conclusion

The JAN2N2919U provides a reliable, low-cost solution for a variety of low-frequency, low-power applications. It has a wide variety of features, including internal bias circuitry, adjustable source current output, and multiple protective features, making it a particularly attractive option for applications that require a wide range of parameters or where thermal protection and current limiting are a priority. Its 4-bit binary configuration and adjustable resistance further enhance its flexibility and make it a cost-effective solution for many applications.
