MAX5907EEE+

PMIC - Hot Swap Controllers

The MAX5907EEE+ hot swap controller is designed to ensure that a system can be safely powered up, down or removed while the load is connected. It is an ideal component for applications where overvoltage, overcurrent, overtemperature and undervoltage protection are needed. The MA5907EEE+ hot swap controller is suitable for various applications such as industrial automation, optical networks, vehicles and medical equipment.

Working Principle

The MAX5907EEE+ hot swap controllers are designed to prevent power supply collapses due to voltage or current spikes during system start–up or after the power supply is inserted. Its main function is to protect the system from high-voltage surges, overvoltage conditions, or overcurrent spikes. It also provides lock–out protection by sensing an overvoltage condition, preventing the damage to power supplies that may occur in such circumstances. Furthermore, hot swap controllers offer an automatic shutdown of the load in the event of an overcurrent situation.

The MAX5907EEE+ hot swap controllers typically include diagnostic LEDs that indicate the status of the overvoltage, overtemperature, and overcurrent protection circuits. These devices also include an on–chip comparator to detect an undervoltage condition. This allows the hot swap controller to act as a self-protected, voltage-controlled switch.

Applications

The MAX5907EEE+ hot swap controller is mostly used in heavy–duty applications where overvoltage and overcurrent protection, as well as a reliable power–down system, is essential. It is also suitable for medical equipment, automotive systems, telecommunication systems, and industrial control applications. This device is ideal for applications such as PLCs, LEDs, power supplies, and SSDs.

The MAX5907EEE+ hot swap controllers provide overvoltage, overcurrent, and overtemperature protection, as well as an integrated undervoltage warning circuit that not only prevents unwanted inrush currents, but also limits system shutdown costs. The IC also provides overvoltage protection in the case of an open drain fault condition. This can be especially beneficial in applications where a load needs to be safely powered up, down or removed while the load is connected.
