PMIC (Power Management Integrated Circuits) are electronic components that are used to control the power for electronic components and appliances, such as computers and mobile phones. They help regulate the voltage, current, and temperature and can increase the efficiency of the system. Hot Swap Controllers are a type of PMIC and the LM5068MM-1 application field and working principle can be broken down as follows:

LM5068MM-1 Application Field

The LM5068MM-1 is a voltage-mode Hot Swap Controller and Supervisor IC that is used to manage the power-up and power-down sequence of non-isolated DC-DC power converters. It works efficiently with the non-isolated point-of-load (POL) packages and helps reduce the system cost. Other application fields include high-efficiency AC/DC systems, DC/DC converters, industrial systems, power supplies, battery chargers and other power applications. The LM5068MM-1 can ensure secure, reliable, and safe power-on/power-off operations for electronic components.

LM5068MM-1 Working Principle

This dual-channel Hot Swap Controller IC loads the input power from two sources and ensures secure, reliable, and safe power-on/power-off operations for electronic components. It works in two modes - voltage-mode and current-mode.The voltage-mode operation allows the system to detect an over-voltage situation according to the input supply voltage, and current-mode operation allows the system to detect an over-current situation according to the load current. Once an over-voltage situation or over-current situation is detected, the LM5068MM-1 will shut off the input power by switching it to the off-state.

The LM5068MM-1 also allows the user to adjust the Over-Temperature Protection (OTP) threshold across a wide range of temperature ranges. This will ensure that the system protection circuit is actively engaged if the temperature exceeds a preset threshold. In addition, the LM5068MM-1 is optimized to reduce the overall system power consumption by lowering the quiescent current while still providing excellent system performance.

The LM5068MM-1 also features a dedicated under-voltage lockout (UVLO) input pin. This will help protect the device from damage due to input voltage that is below the UVLO threshold. In addition, the UVLO pin also allows the user to select one of three different UVLO thresholds for different applications.

Conclusion

The LM5068MM-1 is a voltage-mode Hot Swap Controller IC that is designed to manage the power-up and power-down sequence of non-isolated DC-DC power converters. It has a wide range of application fields, including high-efficiency AC/DC systems, DC/DC converters, industrial systems, power supplies, battery chargers and other power applications. It has two operating modes - voltage-mode and current-mode - that can detect an over-voltage or over-current situation and switch off the input power. The LM5068MM-1 also features a dedicated under-voltage lockout pin and adjustable temperature protection thresholds to ensure secure, reliable, and safe power-on/power-off operations for electronic components.
