The introduction of the MAX5956AEEE+T into the Power Management Integrated Circuit (PMIC) market has offered an exciting new technology to hot swap controllers. This integrated circuit is the latest in hot swap controllers allowing engineers to control, monitor and protect different applications that require switch-mode power supply (SMPS). The addition of SMPS to this type of controller gives allows users to have a more robust and efficient power management solution.

The MAX5956AEEE+T is a hot swap controller integrated circuit. It provides an all-in-one power management solution for application fields such as telecom and automotive power systems, as well as for portable computing applications. The MAX5956AEEE+T is designed to provide bidirectional current sensing, instantaneous overcurrent detection, short circuit protection, as well as thermal protection. Additionally, the integrated device also provides two independent, highly accurate over-voltage protection (OVP) channels for protecting downstream systems.

The MAX5956AEEE+T hot swap controller uses a linear current sensing technique to monitor the current draw from voltage rails in order to prevent system shutdowns due to overcurrent scenarios. The current sense signal is then amplified, filtered and compared to a reference voltage. This reference voltage can be set by adjusting the resistor on board the device. The device then controls the switch to limit the current draw to the set value when the current draw exceeds the set value.

The MAX5956AEEE+T also has a slew-rate controller. This feature allows users to set different ramp-up/ramp-down rates that prevent the power supply from rapidly discharging current. This feature may be used to prevent sudden power drops while in the process of a system restart. It also helps prevent power supply failures due to sudden loads on system.

The MAX5956AEEE+T also has an over voltage protection (OVP) feature. The OVP feature is designed to protect downstream systems from voltage surges. The device monitors the system voltage and uses a reference voltage to create a threshold for OVP protection. When the system voltage exceeds the reference voltage, the device will shut off the switch and shut down the system. This feature helps ensure that user-designed systems are protected from over voltage conditions.

In addition to the current sense, slew-rate and OVP features, the MAX5956AEEE+T also includes an I2C interface. The I2C interface allows users to communicate with the device in order to adjust settings, monitor performance and control functions. This integrated interface allows users to tune and control the controller, as well as modify settings according to the system requirements.

The MAX5956AEEE+T hot swap controller presents an efficient, cost effective and robust power supply solution for various application fields. Its current sense and protection features offer protection and monitoring capabilities, while its slew-rate control and I2C interface add flexibility and control. Hence, this device may be used programs and systems that require proper power management and protection.
