The Auto Restart feature re-enables the output after a fault condition clears, which simplifies recovery in systems that cannot tolerate a latched-off state. The SC-70-5 (SOT-353) footprint is compact — 2.0 mm × 2.1 mm — and the 0.65 mm pin pitch breaks out easily on two-layer boards.","metaTitle":"TPS22945DCKRG4 load switch, 1.62 V–5.5 V, 100 mA, SC-70-5","metaDescription":"Texas Instruments TPS22945DCKRG4 high-side load switch, 400 mOhm Rds(on), 1.62 V–5.5 V input, 100 mA output, SC-70-5 package, -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)","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"P-Channel","Switch Type":"General Purpose","Rds On (Typ)":"400mOhm","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Voltage - Load":"1.62V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS22945","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"100mA","Supplier Device Package":"SC-70-5","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/757cf5b666ae92b50c934d8001a11260.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22945DCKRG4/alternatives.json"},"ai":{"faq":[{"question":"Can TPS22945DCKRG4 be used for 3.3 V applications?","answer":"At 3.3 V input and 100 mA load, the 400 mOhm typical Rds(on) yields a voltage drop of about 40 mV."},{"question":"Is TPS22945DCKRG4 RoHS compliant?","answer":"The device is listed as RoHS compliant per the manufacturer's standard green packaging.
