Texas Instruments High-Performance Analog Hot Swap Controllers LM5068MMX-1

The LM5068MMX-1 is a hot-swap controller designed for managing power supply connections during the insertion and removal of circuit cards in live systems. It operates within a negative voltage input range of -10V to -90V and features in-rush current limiting to ensure safe board insertion. The device includes active current limiting for rapid response to over-current conditions and provides short-circuit protection. This controller is equipped with a programmable under-voltage and over-voltage shutdown feature, which enhances system reliability by preventing damage from voltage fluctuations. The LM5068MMX-1 also offers a power-good (PWRGD) signal that indicates successful power-up, with configurations available for both active HIGH and LOW states. Additionally, it includes a fault timer to avoid nuisance trips caused by short-duration load transients. The LM5068MMX-1 is housed in a VSSOP-8 package, making it suitable for applications such as 48V power modules, central office switching, and distributed power systems. Its design allows for flexible integration into various electronic systems requiring hot-swap capabilities.
