MAX5903AAETT+T Hot Swap Controllers

Power Management Integrated Circuit (PMIC) Hot Swap Controllers are a semiconductor device designed to control either the voltage or the current of a power supply. As the name suggests, these controllers are mainly used to control the power of a system, allowing it to operate at optimum levels, without having any unexpected issues. The MAX5903AAETT+T is a Hot Swap Controller from Maxim Integrated, a leading manufacturer of PMIC products.The MAX5903AAETT+T Hot Swap Controller is a 5V Hot Swap and power sequencing device, designed for use in applications such as Hot Swap backplanes, Telecommunications equipment, Home Theatre, appliances, and Industrial systems. The chip provides power sequencing in three phases, namely the VCC, DC Switch, and Power-On Reset (POR) phases. The chip’s design enables it to control the power and prevent any potential issues while the system is running.The chip features two functions: Voltage Balance and Current Limit. The Voltage Balance feature ensures that all voltage rails remain within a given voltage range, while the Current Limit feature prevents any current overloads occurring within the system. The MAX5903AAETT+T also contains protection features such as Over-temperature protection, current sense comparators, and thermal shutdown protection.The chip is capable of operating at ultra-low quiescent current (<31uA), and it has a fast start-up time (1ms). The MAX5903AAETT+T can also achieve up to 96% peak efficiency and a low power dissipation of only 0.9W, making it a very efficient Hot Swap Controller.When used in conjunction with a backplane, the MAX5903AAETT+T Hot Swap Controller can provide up to 4 power supplies. It has an input voltage range of 3.3V to 24V, and it can support output voltages of 1.5V to 15V. The chip can also support current levels of up to 20A. The MAX5903AAETT+T also features an Open Drain Lockout signal that can be used to control other devices in the system.In short, the MAX5903AAETT+T Hot Swap Controller is a powerful and efficient device designed to provide power sequencing and control in many different applications. By using the chip, system builders can avoid overloading and protect their systems from any power-related problems.
