If the board runs at 85°C ambient, the 125°C junction rating leaves about 25°C of headroom at full load, so the thermal vias under the pad matter. ## Adjustable current limit sets the trip point The current limit is set with a single resistor from the ILIM pin to ground — no external sense resistor, no voltage drop penalty. This lets you dial the trip threshold to match the downstream load: a 1.5 A USB port, a 3 A motor stall, or the full 5.5 A for a bulk-capacitor charging profile. The status flag output (open-drain, active low) asserts when the switch hits current limit or thermal shutdown, so the system controller can log the fault or retry. ## Industrial temp range and package reality Listed as Active by the manufacturer. The base product number TPS2559 covers several current-limit and package variants, but the DRCT suffix (VSON-10, Tape & Reel) is current production.","metaTitle":"TPS2559DRCT Power Distribution Switch, 5.5 A, 13 mOhm","metaDescription":"Texas Instruments TPS2559DRCT high-side power switch: 5.5 A max output, 13 mOhm Rds(on), adjustable current limit, slew-rate control, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Slew Rate Controlled, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"13mOhm","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","Voltage - Load":"2.5V ~ 6.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS2559","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"5.5A","Supplier Device Package":"10-VSON (3x3)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ebba36dadf070760c454f527027550e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2559DRCT/alternatives.json"},"ai":{"faq":[{"question":"Does TPS2559DRCT have an adjustable current limit?","answer":"Yes. The current limit is adjustable via a single external resistor on the ILIM pin. The switch can be set to protect loads up to the maximum 5.5 A rating. No external sense resistor is needed."},{"question":"Is TPS2559DRCT suitable for USB power switching?","answer":"Yes. The 5.5 A output, adjustable current limit, slew-rate controlled turn-on, and status flag make it a strong fit for USB Type-A and Type-C power ports, especially where the port must survive hot-plug inrush without browning out the 5 V rail."},{"question":"Can TPS2559DRCT be used for load switching in portable devices?","answer":"Yes. The 2.5 V to 6.5 V load supply range covers single-cell Li-ion (3.0 V to 4.2 V) and 5 V USB rails. The low 13 mOhm Rds(on) minimises battery-side conduction loss, and the small 3x3 mm VSON package fits space-constrained PCBs in handheld and battery-powered equipment."},{"question":"What is the closest pin-compatible alternative to TPS2559DRCT in this component family?","answer":"Within the TPS2559 family, the TPS2559D is a pin-compatible variant available in a different package option (e.g., SOIC-8). For the exact VSON-10 footprint, confirm the alternate suffix with the distributor — the base product number TPS2559 shares the same core architecture and adjustable current-limit feature set."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2559DRCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2559DRCT when reusing this data.
