The Texas Instruments TPS2391DGKR is an integrated circuit designed for hot-swapping applications in nominal -48V systems. It supports a wide input supply range from -36V to -80V, with a transient rating up to -100V. This device features programmable current limit, programmable current slew rate, and an enable input (EN).
Key features include a fault timer to prevent nuisance trips and an open-drain fault output (FAULT). The TPS2391 is optimized for use with an external N-channel FET and sense resistor to enable live insertion of plug-in cards and modules. It provides load current slew rate and peak magnitude limiting, easily programmed by the sense resistor value and a single external capacitor. The TPS2391 periodically retries the load in the event of a fault.
This hot swap controller is available in an 8-VSSOP package and is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions.
