Maxim Integrated MAX5917BESE+T Hot-Swap Controller

The MAX5917BESE+T from Maxim Integrated is a robust hot-swap controller designed to enable safe insertion and removal of circuit boards from a live backplane. This device is particularly suitable for applications in servers, storage systems, and networking equipment where system uptime and reliability are critical. The MAX5917BESE+T ensures that the electronic components on a circuit board are protected from the stress of inrush currents and voltage transients during hot-swapping operations.

Featuring an adjustable overcurrent protection and circuit-breaker functionality, the MAX5917BESE+T offers a programmable current limit through an external resistor. This allows for precise control over the inrush current, ensuring compatibility with a wide range of applications and requirements. The device operates over a wide voltage range from 1V to 13.2V, making it versatile for various system voltages.

The MAX5917BESE+T incorporates an internal charge pump to control the external N-channel MOSFET, which in turn manages the power distribution to the load. With its integrated undervoltage lockout (UVLO), the device ensures that the system operates only when the supply voltage is within the acceptable range, thereby protecting the load from undervoltage conditions.

Additional features include thermal shutdown protection, which prevents the device and system from overheating during fault conditions. The MAX5917BESE+T also offers a fault indicator output that provides a signal in the event of an overcurrent or thermal shutdown occurrence, facilitating prompt system response and troubleshooting.

Available in a compact 16-pin narrow SO package, the MAX5917BESE+T is designed for space-constrained applications. Its surface-mount technology (SMT) package allows for efficient assembly processes and a reduced footprint on the PCB.

For engineers and designers looking for a reliable solution to manage power distribution and protect their systems during hot-swap events, the MAX5917BESE+T from Maxim Integrated provides a sophisticated and flexible option to meet those critical needs.
