PMIC - Hot Swap Controllers is a subcategory of programmable integrated circuits used in electronic systems. One of the most prominent products in this group is the LM5066PMHE/NOPB. This component is used in a variety of applications and has its own unique working principle.The LM5066PMHE/NOPB is a dual-output, hot swapping power management integrated circuit (PMIC) device designed for applications that require hot-swap controls. It allows for correct initialization of power rails when power supply voltages are sourced from remote locations, and make sure that the connected load remains powered upon any power interruptions or fluctuations.The LM5066PMHE/NOPB utilizes a hot swap controller that, in turn, enables a soft-start across multiple power rails and ensures safe start-up of system supplies. This protects the connected load from overvoltage and inrush current events. The hot swap controller also has an adjustable current limit and temperature compensation, which allows for further precision.In terms of its application field, the LM5066PMHE/NOPB can be used in hot swappable industrial, automotive, and telecom systems. It also finds its application in transient control and hot swap control of harsh environment applications such as -48V telecom and data processing systems. The main purpose of the LM5066PMHE/NOPB is to monitor and control the start-up of system supplies, allowing for safe powering up of the electronic device and its related components. In addition, the circuit protects the device against over-voltage while hot swapping and allows for current sharing and current limiting to ensure the device is powered correctly. This is done through the controller’s heat sink and fault protection features, respectively. The LM5066PMHE/NOPB also features an open-drain VOVP control pin and an active low overtemperature protection pin. The open-drain VOVP control pin provides an additional level of protection, preventing hot swap power supplies from exceeding the maximum overvoltage threshold. The active low overtemperature protection pin can monitor and control the peak power dissipation in the system.In conclusion, the LM5066PMHE/NOPB is a versatile integrated circuit used in hot swapping and harsh environment applications including industrial, automotive, and telecom systems. It is designed to offer protection from overvoltage and inrush current, as well as over-temperature protection for the device. Additionally, it features an adjustable current limit and temperature compensation for increased accuracy.
