Maxim Integrated MAX5987AETE+T Hot-Swap Controller
The MAX5987AETE+T from Maxim Integrated is a sophisticated hot-swap controller designed to enable safe insertion and removal of circuit boards from live backplanes. This component is housed in a 16-pin TQFN package and operates with a supply voltage range of 2.7V to 23V, making it a versatile choice for various applications that require hot-swap functionality.
One of the key features of the MAX5987AETE+T is its integrated electronic circuit breaker, which provides precise overcurrent protection. This helps to prevent damage to both the hot-swapped board and the backplane by limiting the current during fault conditions. The device also includes an adjustable overvoltage and undervoltage lockout, ensuring that the power supply remains within safe operating limits.
The MAX5987AETE+T offers an adjustable slew rate for the output voltage, which allows designers to control the inrush current during the board insertion process. This is critical for preventing glitches in the power supply that could reset other boards in the system. Additionally, the device features an auto-retry or latch-off fault management mode, giving system designers the flexibility to choose how the device responds to fault conditions.
For enhanced system monitoring, the MAX5987AETE+T provides an open-drain power-good (PG) output, which can be used to signal downstream devices that the power is stable and within the specified range. This feature is essential for systems that require a reliable power-up sequence.
Maxim Integrated's MAX5987AETE+T is RoHS compliant and operates over an extended temperature range of -40°C to +85°C, suitable for industrial environments. It is an ideal solution for network routers, servers, storage systems, and other telecom/datacom applications where hot-swapping is necessary to minimize downtime and maintain service continuity.
Overall, the MAX5987AETE+T is a robust and reliable hot-swap controller that offers advanced features to ensure safe and efficient power management in critical electronic systems.
