MAX5904ESA+ Hot Swap Controllers

A hot swap controller is a power management integrated circuit (PMIC) designed to safely manage hot swapping of components in a system. The MAX5904ESA+ is a hot swap controller device from Maxim Integrated that provides extensive fault protection to shut down and protect your hot-swap systems from electrostatic discharge (ESD) and dynamic loads. Hot swapping is the insertion and removal of components in a live or powered system without shutting down the system. It is often used to reduce downtime and maintenance costs, as well as improve system reliability. The MAX5904ESA+ hot swap controllers can support robust hot-swap operations and provide system-level protection against ESD and overvoltage (OVP).

Application Field

The MAX5904ESA+ hot swap controllers are widely used in a variety of applications such as portable computing, telecommunications systems, industrial automation, and many other commercial and industrial environments that require fast, secure hot-swapping and reliable process control. These hot-swap controllers are designed to monitor and control the power up and power down of a circuit board in a system, as well as protect against other potentially damaging scenarios like ESD and overvoltage conditions.

Working Principle

The MAX5904ESA+ is a single-channel hot-swap controller that provides robust hot-swapping protection. It monitors the voltage on board components and shuts down the system to protect against ESD or OVP events. It also limits inrush currents while powering up internal components to prevent overloading the voltage supply. In addition, this hot-swap controller features programmable control of open-drain control output, auto-restart delay for load current settling, and adjust the soft-start time for ramping up the load voltage. The device also integrates an adjustable undervoltage lockout (UVLO) and automatic load disconnect. The MAX5904ESA+ also features power-on reset (POR) and integrated filter for short turn-on delay.

The MAX5904ESA+ features low-cost, hot-swapping solution designed for microcontroller-based systems. It provides overcurrent protection with adjustable trips setpoints, enabling robust thermal performance in true-hot-swap applications. The device also features jam electrical fault protection (JEP) with programmable time duration, which terminates a fault during the power-on phase. The hot-swap controller is also protected from external ESD events and can be trimmed with digital or analog input to protect against false triggering of JEP. The MAX5904ESA+ provides superior fault protection and is a great choice for modern hot-swapping products.
