MIC2583R-LBQS application field and working principle

PMIC - Hot Swap Controllers has been prevalent in many industrial and commercial areas. The MIC2583R-LBQS Hot Swap Controllers or HSMC is one of the leading PMIC ICs, offering a wide range of application fields and cost-effective power solutions. The MIC2583R-LBQS HSMC provides complete control for Hot Swap load sharing, an inherent characteristic of a multi-PCB system design. The MIC2583R-LBQS is a programmable Hot Swap MOSFET controller that features low quiescent current, high level of power dissipation, high switching frequency and excellent thermal performance.

The MIC2583R-LBQS controller offers many benefits, including advanced power cycling detection, accurate current sensing, slew rate control, low current startup capability and advanced I2C programming and control. By providing a cost effective, reliable and efficient solution for Hot Swap multi-PCB designs, the MIC2583R-LBQS HSMC is ideal for use in various applications in the industrial, automotive, medical and consumer markets.

Working principle

The MIC2583R-LBQS HSMC works by providing an interface between the power MOSFET and an external control method. This control method is typically an I2C bus, but can also be an additional MOSFET such as a differential MOSFET, a SMBus, or any other digital or analog interface. The goal of the controller is to ensure that the power delivery of each MOSFET is regulated and that the system remains in balance.

When the HSMC is enabled, it begins to sense the current of each Hot Swap MOSFET and the system assumes the power-sharing condition. To ensure a balanced and fault-free system, the HSMC continuously measures current through each driving MOSFET and attempts to establish a near constant power distribution condition across the entire Hot Swap system.

The HSMC is capable of detecting an overcurrent fault in either the discharge or charging phase and will then track the current of the fault MOSFET and enforce a fast turn-off action. This helps to quickly and safely discharge the load, thus protecting the system from further damage.

The MIC2583R-LBQS is also capable of sequencing multiple devices in order to facilitate a load distribution strategy. This is accomplished by utilizing its programmable slew rate and power-fail timer to accurately control the timing of each device’s turn-on and turn-off actions.

As the Hot Swap system begins to lose power, the HSMC will signal an immediate shut-down to all MOSFETs using an integrated power-fail timer. The device can also be used to remotely switch off the Hot Swap system, without the need for manual intervention.

Applications

The MIC2583R-LBQS HSMC is used in a variety of applications. It is ideal for use in distributed bus systems, where multiple Hot Swap MOSFETs must be controlled accurately and efficiently. It is also great for powering system upgrades, increasing multiple system outputs and providing cost effective, reliable and efficient Hot Swap solutions for various industrial, automotive, medical and consumer markets.

In addition, the MIC2583R-LBQS HSMC can be used to sequentially power-up devices, allowing the system to be powered up in a predetermined order. It can also be used to control the rate of change of bus voltage to reduce transients in a multi-rail system.

In addition to these features, the MIC2583R-LBQS also offers various safety features and fault protection for improved system reliability. These include overvoltage and undervoltage protection, overcurrent and over-temperature protection, and ESD protection.
