Power Management Integrated Circuit (PMIC) - Hot Swap Controllers are a component of a power subsystem for a variety of applications. They provide reliable power inputs and outputs and also help protect from over-voltage, over-temperature, and over-current conditions. The MAX5900AAETT+T is a power management integrated circuit (PMIC) designed specifically for Hot Swap® applications, featuring an integrated Hot Swap controller and integrated current-limiting FETs.

The MAX5900AAETT+T Hot Swap controller features an adjustable current limit and an adjustable turn-off threshold. The MAX5900AAETT+T also includes an enable input for under-voltage lockout (UVLO) control and a fault indicator.

The MAX5900AAETT+T is a single-chip solution for Hot Swap controllers and is typically used in systems that require accurately controlled voltage and current sources. It is suitable for a wide range of industrial, automotive, and consumer applications, such as notebook and desktop personal computers, servers, and industrial control systems.

Application Field

The MAX5900AAETT+T can be used in applications that require controlled current and voltage sources, such as notebook and desktop personal computers, servers, and industrial control systems. It is designed to provide a reliable power supply in these systems, while also protecting against over-voltage, over-temperature, and over-current conditions.

The device is ideal for applications that require Hot Swap protection, such as servers and industrial control systems. It is also suitable for consumer and automotive applications, such as battery pack protection and mobile device protection. The device offers an adjustable current limit and adjustable turn-off threshold, as well as an enable input for UVLO control and a fault indicator.

Working Principle

The MAX5900AAETT+T operates using two main operating modes. The first is an active mode, which is activated when an external input-ON signal is given. In active mode, the output voltage is regulated based on the voltage detected at the power input.

The second mode is a standby mode, which is activated when the input-ON signal is removed. In standby mode, the device will remain in low power mode, but still monitor the input voltage. If the input voltage exceeds a set threshold, the device will switch to active mode and regulate the output voltage.

The device also has a wide range of features to protect against over-voltage, over-temperature, and over-current conditions. It features an adjustable current limit which can be adjusted to set a range of values that limit the magnitude of the output current. Additionally, the device has an adjustable turn off threshold which will cause the device to turn off if the output voltage exceeds a predetermined level. The device also has an enable input for under-voltage lockout control, which prevents the device from turning on when the input voltage is below a certain level. Additionally, the device includes a fault indicator for quick and easy fault detection.

The device is easy to use and is a reliable and efficient solution for Hot Swap applications. The device is ideal for industrial, consumer, and automotive applications which require power input and output control.
