Maxim Integrated\'s MAX8533EUB+T is an integrated Hot Swap controller designed for safe and efficient Hot Swap applications such as in telecom and server racks, avionics systems, battery-powered medical and industrial equipment, etc. This Hot Swap controller supports mains or local power supply sources and offers both load disconnect and inrush current limiting while ensuring no hazardous “cold-start” conditions. The MAX8533EUB+T also includes all of the circuit protection features required to comply with advanced safety and reliability standards.

The main features of the MAX8533EUB+T are as follows:

• 3-level Hot Swap power management and current limiting
• Bi-directional load current sensing
• Thermal protection solution
• Programmable faults and shutdown handling
• Programmable Digital High-speed GPIOs
• Proprietary active load capacitor (ALC) and software-programmable capacitor (SPC) solutions

The MAX8533EUB+T works using a 3-level protection paradigm. The first level of protection is the Hot Swap switch, which is responsible for ensuring that the load is powered off when there is no application power present. This switch is also responsible for preventing inrush currents when connecting the switch to the load. The second level of protection is the limit current feature that is used to limit the input/output current when it exceeds the programmed threshold. This feature is also used to regulate the voltage level of the output. The third level of protection is the over-voltage protection (OVP) and under-voltage protection (UVP) features. The OVP feature is used to prevent a device from being powered up when the voltage is exceeds the maximum allowed, while the UVP feature is used to shut down the device when the voltage drops too low.

In addition to the 3-level protection provided by the MAX8533EUB+T, it also offers several other benefits. One of these is its open-drain MAX factor core, which enables it to be powered from a variety of sources, including mains or local power supplies. It also offers a low quiescent current of just 32 μA, making it ideal for energy-sensitive applications. In addition, it includes programmable digital high-speed GPIOs, allowing it to be connected to a variety of peripheral devices. It also includes proprietary active load capacitor (ALC) and software-programmable capacitor (SPC) solutions, which can be used to provide additional current and voltage regulation.

Overall, the MAX8533EUB+T is an ideal solution for Hot Swap applications such as telecom and server racks, avionics systems, battery-powered medical and industrial equipment, and more. With its 3-level protection, open-drain MAX factor core, low quiescent current, programmable digital GPIOs, and proprietary ALC and SPC solutions, the MAX8533EUB+T is designed to ensure safe and efficient Hot Swap operation.
