The MAX5917BESE+ from Maxim Integrated is a state-of-the-art hot swap controller designed to enable safe insertion and removal of circuit boards from a live backplane. This component is particularly useful in systems where maintenance or upgrades need to be performed without shutting down the entire system, such as servers, telecom equipment, and data centers.

Key Features

• Integrated MOSFET: The device features an internal MOSFET which simplifies the design and reduces the number of external components required.
• Adjustable Overcurrent Protection: The MAX5917BESE+ allows for precise setting of overcurrent protection threshold through an external resistor, providing flexibility to accommodate various load requirements.
• Undervoltage Lockout (UVLO): It includes a UVLO feature that ensures the controller operates only when the supply voltage is within an acceptable range, protecting the system from low-voltage conditions.
• Programmable Startup Time: The startup time is programmable, allowing for controlled inrush current during system power-up.
• Thermal Shutdown: The device also incorporates thermal shutdown to prevent damage from excessive heat.

Applications

The MAX5917BESE+ is ideal for a variety of applications where board level power control and protection are critical. These include:

• Redundant Power Supplies
• Storage Systems
• Network Routers and Switches
• Base Stations
• Industrial Control Systems
