It is designed for handheld and mobile devices where the system must seamlessly switch between a battery, a USB VBUS, and an external adapter without back-feed between the sources. The internal P-channel FETs eliminate the need for external blocking diodes, reducing BOM count and forward voltage drop. With a supply range from 2.5 V to 12 V, it covers single-cell Li-ion through multi-cell or USB-C PD rails. ## 75 mA per output — enough for sensor rails and low-power peripherals Each of the two outputs is rated for a maximum continuous current of 75 mA. This suits the part for power-gating sensor rails, low-power MCU I/O banks, Bluetooth/Wi-Fi module supplies, or audio codec rails — not for main processor or display backlight paths. The turn-on delay is 65 µs and the turn-off delay is 32 µs, which allows the downstream load to settle before the supply is switched. The 2 mA supply current is the quiescent draw of the control logic itself, not the load current. ## Industrial temperature grade and 8-UQFN footprint The 8-UQFN package (1.5 mm × 1.5 mm) requires a fine-pitch layout and a clean solder-paste stencil aperture for the thermal pad. ## Active production — no immediate LTB risk","metaTitle":"TPS22933ARSER Source Selector Switch, 75mA, 2.5V-12V, 8-UQFN","metaDescription":"TI TPS22933ARSER P-channel source selector switch, 3:2 ratio, 75 mA max output, 2.5V-12V supply, 8-UQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Source Selector Switch","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"P-Channel","Applications":"Handheld/Mobile Devices","Mounting Type":"Surface Mount","Package / Case":"8-UFQFN","Product Status":"Active","Delay Time - ON":"65 µs","lifecycle_stage":"eol_hot","Current - Supply":"2 mA","Delay Time - OFF":"32 µs","Voltage - Supply":"2.5V ~ 12V","Internal Switch(s)":"Yes","Base Product Number":"TPS22933","Ratio - Input:Output":"3:2","Operating Temperature":"-40°C~85°C","Current - Output (Max)":"75mA","Supplier Device Package":"8-UQFN (1.5x1.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4395","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5ec7323816d3262da1cb4d9bf75d948d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22933ARSER/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS22933ARSER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS22933ARSER when reusing this data.
