LM5067MM-2

Power Management Integrated Circuit (PMIC) and Hot Swap Controllers are becoming increasingly important in electronics and power systems. With power shortages and with the rapid technological advances in electronics, there is an ever increasing need to better manage the power requirements of electronics. This management is extremely important in order to ensure the efficient use of power and, when needed, the safeguarding of the system from a power surge or overload.

The LM5067MM-2 is the latest hot swap controller from Texas Instruments. It is designed to provide efficient and reliable management of the power supply to hot-swappable electronic modules. This makes it ideal for use in applications where hot-swappable modules are used for quick product development or for systems that require frequent updates, such as in network environments.

The LM5067MM-2 controller provides a wide range of features including integrated gate drive and Soft Start/Soft Stop sequencing, as well as under-voltage and over-current protection. It has a high bandwidth (5.5MHz) and is able to operate up to 50V with 4A rating. The device has been designed to operate at high frequencies and with its low-side gate drive, it has the potential to provide higher power system efficiency. Additionally, the LM5067MM-2 has an integrated FET which eliminates the need for an external switch.

In terms of application fields, the LM5067MM-2 is suitable for use in high performance hot-swap designs in server/storage systems, switch-mode power supplies (SMPS), telecommunications systems and hot-swap electronic module applications.

In terms of its working principle, the LM5067MM-2 uses its integrated FET to switch the hot-swappable module on and off. The device is able to monitor the status of the load and it can detect changes in the load and associated power supply indicaitors. This allows the controller to detect a fault condition and shut down the power supply to the module quickly, preventing any potential damage to the module. Additionally, the LM5067MM-2 can adjust the DC power sequencing and sequencing delay time according to the specific requirements of the system.

The LM5067MM-2 is a powerful and versatile hot swap controller. It provides an ideal solution for efficient power management in hot-swappable module applications. Its integrated gate drive, under-voltage, over-current protection, low-side gate drive and adjustable DC power sequencing and sequencing delay time make it well suited to a range of applications.
