Each of the two N-channel outputs delivers up to 2.5 A continuous, with a typical on-resistance of 44 mOhm — the conduction loss at 2.5 A is roughly 275 mW per channel, which the 10-VSON exposed pad must sink to the board. The switch is self-contained: no external Vcc supply is needed, and the On/Off interface accepts a non-inverting logic signal. The slew-rate controlled turn-on limits inrush current, and the open-drain status flag reports overcurrent or thermal fault conditions. ## Parametric fit: Rds(on), input range, and protection The 44 mOhm typical Rds(on) at 2.5 A sets a voltage drop of roughly 110 mV per channel — low enough to keep a 5 V USB rail above the 4.75 V minimum under full load. The load voltage range of 2.5 V to 6.5 V covers 3.3 V and 5 V rails, and the device does not require a separate bias supply. Fault protection includes adjustable current limiting (set with an external resistor), over-temperature shutdown, and undervoltage lockout. The 1:2 input-to-output ratio means a single enable signal gates both channels simultaneously — useful for ganged power domains. ## Package, temperature grade, and sourcing posture The 10-VSON package (3x3 mm, 0.50 mm pitch) with exposed pad requires a thermal land on the PCB — the datasheet recommends a 2.8x2.8 mm pad with at least four thermal vias to the ground plane.","metaTitle":"TPS2561ADRCT Texas Instruments Power Switch – 2.5 A, 44 mOhm","metaDescription":"TPS2561ADRCT dual-channel high-side power switch from TI. 2.5 V–6.5 V input, 44 mOhm Rds(on), 2.5 A per channel, adjustable current limit, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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)":"44mOhm","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":"2","Base Product Number":"TPS2561","Output Configuration":"High Side","Ratio - Input:Output":"1:2","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"2.5A","Supplier Device Package":"10-VSON (3x3)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6800","priceTiers":[{"qty":1,"price":"$1.68000","currency":"USD"},{"qty":10,"price":"$1.50100","currency":"USD"},{"qty":25,"price":"$1.42480","currency":"USD"},{"qty":100,"price":"$1.17020","currency":"USD"},{"qty":250,"price":"$1.09392","currency":"USD"},{"qty":500,"price":"$0.96672","currency":"USD"},{"qty":1250,"price":"$0.76320","currency":"USD"},{"qty":2500,"price":"$0.72000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4bb09e2bf10b2afcb6132704f422050b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2561ADRCT/alternatives.json"},"ai":{"faq":[{"question":"How can I order TPS2561ADRCT or request a quote?","answer":"TPS2561ADRCT is active and ROHS3 compliant.
