MAX5916EUI+ is a hot swap controller from Maxim Integrated. It provides operating voltage to safely bring up or power down hotswap system used in computing and networking applications. This hot swap controller works based on Adaptive Voltage Positioning (AVP) technique. It is a low quiescent current monolithic IC designed specifically to drive external P-channel MOSFETs.

As the name suggests, a hot swap controller is used to allow the insertion and removal of a card or component while the system is running. In computing, hot swapping refers to the replacement of a component without powering down the computer. Hot swapping is used in systems where it is important to have minimal downtime, like servers, industrial manufacturing and test benches. It can also be used to minimize energy costs. Hot swapping fundamentals include a host system that provides the power, interconnects and control interfaces, a controller or switch for controlling the power on/off, and a sensing device to provide feedback on the condition of the component.

The MAX5916EUI+ hot swap controller is optimized for computing and networking systems, providing up to 10V at up to 2A. It works on AVP technology for reliable system operation, adaptive inrush and overcurrent control, and eliminating thermal runaway conditions. It is capable of auto-sensing and adapting to input voltage variations. It also provides status indication of which faults have been detected along with the ability to detect current sense and sense temperatures.

The MAX5916EUI+ hot swap controller operates in two different modes: active mode and sleep mode. In active mode, the controller monitors the load current, output voltage and temperature events. In sleep mode, the controller turns the MOSFET off by sinking current and reduces quiescent current. The MAX5916EUI+ hot swap controller also features external resistor-programmable voltage supervision, bringing up to 6V of additional headroom, adjustable slew rate, hysteresis, positive and negative current limit settings, and more.

The MAX5916EUI+ hot swap controller is used in a wide range of applications. From computer systems, storage devices, solid-state drives and network switches, to point-of-load converters and system boards, the MAX5916EUI+ is perfect for hot swapping components with minimal downtime. It is also suitable for industrial, automotive and medical applications, providing reliable and safe power sequencing.

In summary, the MAX5916EUI+ hot swap controller from Maxim Integrated is a low quiescent current monolithic IC designed specifically to drive external P-channel MOSFETs used in hot swap applications. It works on Adaptive Voltage Positioning (AVP) technology, providing up to 10V at up to 2A. The controller features external resistor-programmable voltage supervision, bringing up to 6V of additional headroom, adjustable slew rate, hysteresis, positive and negative current limit settings, and more. It is used in a wide range of computing and networking applications, providing reliable and safe power sequencing.
