The MAX5920BESA + is a precision hot swap controller designed to provide precisely controlled inrush, power sequences and control over output powered devices based on high and low-side overcurrent detection, preventing typically high inrush current peaks and unwanted high power levels. With a logic voltage range of 3V to 5.5V, the MAX5920BESA + is suitable for a variety of applications, ranging from industrial and office equipment to notebook PCs and high-end servers.

The MAX5920BESA + features absolute maximum ratings of 16A for the positive, negative and enable pins, and maximum power ratings of 13A and 10A respectively. This makes it an excellent choice for applications where high power levels are required, such as server power supplies, medical equipment, industrial equipment, and data center applications. In addition, the device is capable of detecting and responding to both pre- and post-fault conditions nearly instantaneously.

The MAX5920BESA + features an advanced high-current buck topology, with the ability to synchronize its PWM outputs with the host board\'s operating frequency. This feature helps ensure that the supply voltage is kept within acceptable parameters, even under extreme load conditions. The device also features a unique mode that allows it to regulate the current limit as the output power increases. This limits the short-term peak current, protecting the device from possible damage.

The MAX5920BESA + features a negative voltage detect function, which allows the device to detect faults in negative supply rails and react accordingly. The device can also be used in conjunction with external N-type Mosfets to limit inrush current and resolve any voltage or current spikes. This makes the MAX5920BESA + ideal for systems with DC/AC single-rail converters, such as voltage isolation and protection circuits.

The MAX5920BESA + has a comprehensive set of safety features, including thermal protection, overvoltage protection and fault protection. Additionally, the device can be used with external current-limited N-type MOSFETS to further enhance its capabilities. The MAX5920BESA + also offers Hot Swap ESD protection, which helps protect against both overvoltage and short-circuit failure from the user’s equipment.

The MAX5920BESA + features input and output control pins, allowing for bidirectional communication between the system and the device. This makes it easy to integrate the device into virtually any system. The device also features a slew rate controlled output, which can be used to reduce output voltage transients. This feature helps ensure that the system remains safe and stable even during extreme short-term power surges.

In summary, the MAX5920BESA + is an excellent PMIC Hot Swap controller that provides high power levels, accurate output control, and pre- and post-fault protection. Its compact size and wide voltage range make it ideal for a variety of applications, from industrial and office equipment to high-end servers. With an impressive array of safety features, the MAX5920BESA + ensures that your systems will remain operational even when faced with severe short-term fault conditions.
