The MAX5954AETX+ is a hot swap controller designed to safely power up and power down systems containing hot pluggable load circuit boards, under the category of PMIC (Power Management Integrated Circuit). With its ability to power up and power down high voltage systems with hot pluggable load circuit boards, this hot swap controller is suitable for applications such as power supply load boards and processor boards with hot plug capability.
The MAX5954AETX+ is a high-efficiency, gate driver-based hot swap controller capable of supplying up to 1A of output current and up to 28V of output voltage. Using an onboard oscillator, the MAX5954AETX+ can be configured to operate in either continuous or periodic hot swap mode. In continuous mode, the device continuously supplies the current to the load board until it is powered down. In periodic mode, the device will periodically supply current for a predetermined time period and then switch off for the same period of time. This allows the device to conserve energy as well as reduce wear and tear on the component.
The primary functionality of the MAX5954AETX+ is to monitor the current, voltage and temperature of the hot pluggable load circuit board while it is plugging in. The device is equipped with two voltage and current monitoring channels, each with its own programmable high and low trip points. The high and low trip points can be used to set the minimum and maximum safety levels for the load, and any load exceeding these trip points will cause the MAX5954AETX+ to shut off its output voltage to prevent possible damage.
The MAX5954AETX+ also has a temperature monitoring feature, which uses an internal thermistor to detect the temperature of the load board. The temperature monitoring feature is designed to protect the load board from overheating, and the onboard thermal protection circuit will shut off the output voltage when the temperature is detected to be too high for safe operation. The temperature monitoring feature can also be used to detect anomalous conditions such as thermal runaway, which can be indicative of an impending failure.
The MAX5954AETX+ also features a slew-rate control output, which can be used to reduce the inrush current of the load board. This helps to prevent spikes in the current when the load board is turned on, which can potentially damage the board or other surrounding components. Additionally, the MAX5954AETX+ can be used to power up the load board in a sequential order, to reduce the total current spike.
Finally, the MAX5954AETX+ includes a diagnostic comparator with programmable trip points, which can be used to detect faults in the power supply and load board. In the event of a fault, the comparator can output a fault signal to the system controller, allowing the controller to take corrective action. It also includes overvoltage protection and external reference adjustment features, giving the user the ability to customize the operating parameters of the device.
In conclusion, the MAX5954AETX+ is a feature-rich hot swap controller designed for use in applications with hot pluggable load circuit boards. It is equipped with voltage, current, and temperature monitoring features, as well as slew control and fault detection features. These features allow the device to protect the load board from faults, as well as optimize the operation for optimal performance, making it a great choice for applications that need hot plug capability, such as power supply and processor boards.
