It manages the inrush current when a line card is plugged into a live -48V rail, using an external N-channel MOSFET as the pass element — there is no internal switch. The controller integrates undervoltage lockout (UVLO) and latched fault protection, and gives you programmable control over current limit, fault timeout, and output slew rate via external components. ## Supply range and temperature grade — what they mean for your BOM The supply range is -80V to -36V, which directly covers the standard -48V telecom nominal with healthy margin for transients. The operating temperature range of -40°C to 85°C is industrial grade — it will hold up in an outdoor telecom cabinet or an unventilated factory floor. If your design lives in a temperature-controlled data center, that is still fine, but the part is not rated for under-hood automotive or downhole environments. ## Programmable features and what they buy you You can set the current limit, fault timeout, and output slew rate with external resistors and a capacitor. That means you can tailor the inrush profile to the bulk capacitance on your card — slow the slew rate for a large capacitor bank, or set a tight fault timeout to catch a short before the backplane breaker trips. The latched fault behavior means once a fault is detected, the controller shuts off and stays off until you cycle the power or the enable signal — no automatic retry, which is the safer choice for a -48V system where an auto-retry could hammer the backplane. ## Package and mounting — field-service reality It comes in an 8-VSSOP package (3.00 mm width), surface mount. That is a small outline, fine-pitch part — not something you swap in a parking lot with a soldering iron. ## Lifecycle and sourcing The TPS2398DGK is listed as Active in production — no end-of-life notice, no last-time-buy risk. It is ROHS3 compliant.","metaTitle":"TPS2398DGK Hot Swap Controller, -48V, 8-VSSOP","metaDescription":"TI TPS2398DGK hot swap controller for -48V telecom systems.
