Introduction

The DMA2610H0R is a type of transistor array with pre-biased outputs, which allows easy and convenient driving of multiple outputs from the same source. It is employed in a variety of applications including low power switching, power sequencing and protection applications, and peripheral power sequencing. It is commonly used as a single IC solution for applications that require low on-resistance and high current carrying capacity. This article will discuss the application field and working principle of the DMA2610H0R.

Function and Working Principle

The DMA2610H0R comprises two N-Channel MOSFETs and two P-Channel MOSFETs with their respective gates and sources pre-biased. This type of transistor array allows for the efficient control of multiple outputs simultaneously, with only one input source required. The outputs each consist of a single gate channel, a source channel, and a guard channel. The gate channel provides the voltage supply or gate control, while the source is connected to a ground or neutral voltage. The guard channel is connected to a steady DC voltage, which maintains a constant bias on the output.The DMA2610H0R can be operated in two different modes. In the “fixed output mode”, all outputs will remain in the same state for as long as the gate and guard voltages remain the same. In the “dynamic control mode”, the driver circuit can change the states of the outputs depending on the input signals. This mode is more useful in applications that require multiple power sequencing and protection functions.

Applications

The DMA2610H0R is ideal for low power switching and peripheral power sequencing, as it allows for easy and reliable control of multiple outputs simultaneously. It is also widely used in applications such as computer systems, audio systems, power supplies, and lighting systems, as the ability to control multiple outputs helps to reduce the number of components and simplify the overall design.The output currents of the DMA2610H0R are also capable of delivering up to 0.5Amp in a continuous mode, making it an ideal solution for applications that require high current capacity or current sharing. It also provides protection functions and can be used in applications such as over-current protection and over-voltage protection.

Conclusion

The DMA2610H0R is a transistor array with pre-biased outputs, which allows for the efficient and reliable control of multiple outputs from a single input source. It is particularly useful in low power switching and power sequencing applications, as the ease of control allows for lower component count and simpler design. The DMA2610H0R is also capable of delivering up to 0.5 Amp in a continuous mode, making it an ideal solution for applications where high current capacity or current sharing is required.
