Maxim Integrated MAX5939EESA+T Hot-Swap Controllers

The MAX5939EESA+T from Maxim Integrated is a sophisticated hot-swap controller designed to enable safe board insertion and removal from a live backplane. This compact and efficient device is housed in an 8-pin NSOIC package and is supplied in tape and reel form, making it ideal for high-volume production applications.

With a wide operating voltage range of 1V to 13.2V, the MAX5939EESA+T provides versatile performance suitable for various system voltages. It is engineered to protect system power supplies and electronic equipment by limiting the inrush current during plug-in, which helps to prevent glitches on the power supply rail and reduces the risk of damage to connectors and circuit components.

The device features an integrated charge pump that drives an external N-channel MOSFET, allowing for precise control of the inrush current through the MOSFET's gate. The MAX5939EESA+T's programmable current-limit threshold can be set with a single external resistor, providing flexibility to accommodate different design specifications and requirements.

Additional safety features of the MAX5939EESA+T include thermal shutdown protection, which prevents overheating, and an under-voltage lockout (UVLO) that ensures the device operates only when the supply voltage is within an acceptable range. An auto-retry feature is also included, which allows the device to automatically attempt to re-enable the MOSFET following a fault condition.

The MAX5939EESA+T offers a unique combination of protection features, compact size, and ease of use, making it an excellent choice for a variety of applications, including servers, storage systems, and telecommunications equipment. Its robust design ensures reliable operation and system integrity, providing peace of mind for engineers and system designers tasked with safeguarding sensitive electronic components.

Maxim Integrated's commitment to quality and performance is evident in the MAX5939EESA+T, which is designed to meet the stringent requirements of modern electronic systems, ensuring both efficiency and reliability in hot-swap applications.
