If you need to control multiple devices, an array of transistors and pre-biased transistors such as the DMC-964-070R can be a great deivce. The DMC-964-070R is a complete NPN array that is pre-biased, which means that the collector-emitter is already connected, reducing the cost and complexity when designing multiple projects. This device contains six NPN transistors and includes emitter resistors and reverse bias circuitry.

The application field of this array is extremely varied, but it’s often used as motor drivers, light drivers, load switches and as current mirrors. The reverse bias circuitry ensures that the VBE is clamped to the REV voltage, so it’s well suited for driving inductive loads such as motors and solenoids, which require reverse bias protection to keep MOSFETs in their off state. It also has other protection features that make it a great choice for applications such as power regulation, which require precision control of current flow.

The working principle of the DMC-964-070R is quite simple, although it does take some knowledge of basic transistors and circuits. The device contains six NPN transistors connected in series, each with a separate emitter resistor. When the device is powered, each transistor is forward biased, allowing current to flow through them. The series connection of the transistors ensures that the same current passes through each transistor, so that the amount of current can be precisely controlled by adjusting the amount of voltage that is applied to the device.

The reverse bias circuitry of the device is also very important, as it ensures that the voltage between the base and emitter of the transistors remains stable and always clamped to the REV voltage. This helps to protect the transistors and stabilizes the current flow. Furthermore, the reverse bias circuitry is designed to also protect the transistors in case of an overload, automatically shutting off the current flow if the voltage exceeds the REV voltage.

The DMC-964-070R is an excellent device for controlling multiple devices, as it contains six transistors in one package, which can save time and cost when designing projects. It is suitable for a variety of applications, including motor drivers, load switches, current mirrors and power regulation. Furthermore, the pre-biased connection and protection features make this device an ideal choice for applications that require precision control and reverse bias protection.
