PMIC - Hot Swap Controllers

The MAX5955AEEE+ is a 1.5A hot swap controller with current balancing for up to four cabinets. It provides a safe, reliable and complete monitoring and control solution for hotswap power management applications. For applications requiring multiple rails, the MAX5955AEEE+ allows each rail to be hot swapped, providing a solution with a current step of up to 1.5A. With up to 4 logic-controlled input and output pins, it can switch multiple connections on and off together. In addition, it can easily reverse the voltage of adjacent pins, allowing simultaneous supply and removal of power over a single pin. It includes protection features such as automatically turning on output as soon as input voltage is applied, and automatically turning off output when input voltage is absent. Furthermore, the MAX5955AEEE+ fully integrated negative charge pump extends the PCIe range to -0.5V, allowing appropriate voltage drops when driving large currents.

The MAX5955AEEE+ is specifically designed for applications in the data center, Telecommunications, Transportation and Medical fields. In applications requiring multiple racks, the MAX5955AEEE+ can easily provide a redundant connection between racks and facilitate addition or removal of racks. In addition, the device can deliver up to 1.5A of current with a peak current of up to 3A to provide sufficient power for various applications. Its fast delay and low shutdown current feature also ensure fast electrical connection operations.

Working principle

The MAX5955AEEE+ starts when a source voltage is applied to the input pin. Once the voltage is greater than the undervoltage threshold, the device will delay the output voltage suppressor (OVS) and turn on the output. In addition, the device also implements auto-false feature (AFL) to detect a predetermined current over the driver\'s turn_on/turn-off threshold. When the current rises above this threshold, the AFL output changes from low to high, indicating that a successful power on/off operation has occurred. In addition, additional protection protection is also provided for overvoltage, overcurrent, and overtemperature situations.

When the output is turned off, the device waits for a period of time for the disconnection to take place before turning off the OVS. This prevents excessive power consumption due to inrush currents during connection or disconnection. The MAX5955AEEE+ also offers current sharing capability, enabling the connection and disconnection of multiple outputs while maintaining a single load current.

The MAX5955AEEE+ is compliant with several international standards and industry specifications, including FCC Part 68, EN 60950, ITU-T K.21, ANSI C37.90, and Power-over-Ethernet (PoE) 802.3af standards. In addition, its high-speed interface and smart configurable options allow the host processor to access device status information and control output voltage level.

Conclusion

The MAX5955AEEE+ offers a safe, reliable, and complete solution for hot swap power management applications. Its fast turn on/off times and current sharing capability make it ideal for a variety of applications in the data center, Telecommunications, Transportation and Medical fields. Its protection features provide reliable protection for overvoltage, overcurrent, and overtemperature conditions. The MAX5955AEEE+ is compliant with international standards and industry specifications, allowing compatibility with a variety of systems. Finally, its high-speed interface and smart configurable options allow the host processor to access device status information and control output voltage level.
