The slew-rate controlled turn-on limits inrush current when switching capacitive loads, which matters when the downstream rail powers a Wi-Fi module or a sensor cluster that would otherwise droop the input supply. At 4.7 mOhm typical, the TPS22970YZPT sits in the mid-range of TI's load-switch portfolio — lower than the TPS22918 (which runs around 20 mOhm) but not as aggressive as the TPS22976 (which can go below 2 mOhm). For a 3 A load, the voltage drop is roughly 14 mV, which keeps the output rail within tight tolerance for a 1.2 V core supply. The 4 A maximum continuous rating is a steady-state limit; the part can handle brief peaks above that, but the datasheet's pulsed-current curve should be consulted for transient events. It is ROHS3 compliant. The 8-DSBGA package is a 0.5 mm pitch wafer-level chip-scale package — not hand-solderable without a hot-air station or reflow oven, but standard for high-volume pick-and-place. Tape & Reel and Cut Tape options are listed, which suits both prototyping and production runs. The 8-DSBGA is a 0.5 mm pitch, 8-ball array, approximately 1.5 mm × 1.5 mm. The supplier device package is 8-DSBGA. The small footprint saves board space but requires a 4-layer PCB for fan-out of the center balls. Surface-mount only. No through-hole variant exists. The input-to-output ratio is 1:1, so it is a simple pass-gate — no charge pump or boost converter inside.","metaTitle":"TPS22970YZPT Texas Instruments Load Switch – 4 A, 4.7 mOhm","metaDescription":"Texas Instruments TPS22970YZPT load switch: 4 A continuous, 4.7 mOhm typical Rds(on), 0.65 V–3.6 V range, slew-rate controlled, 8-DSBGA, -40°C to 105°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","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"4.7mOhm","Mounting Type":"Surface Mount","Package / Case":"8-XFBGA, DSBGA","Product Status":"Active","Voltage - Load":"0.65V ~ 3.6V","lifecycle_stage":"eol_hot","Fault Protection":"-","Number of Outputs":"1","Base Product Number":"TPS22970","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~105°C(TA)","Current - Output (Max)":"4A","Supplier Device Package":"8-DSBGA","Voltage - Supply (Vcc/Vdd)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3400","priceTiers":[{"qty":1,"price":"$1.34000","currency":"USD"},{"qty":10,"price":"$1.19500","currency":"USD"},{"qty":25,"price":"$1.13360","currency":"USD"},{"qty":100,"price":"$0.93130","currency":"USD"},{"qty":250,"price":"$0.87056","currency":"USD"},{"qty":500,"price":"$0.76934","currency":"USD"},{"qty":1250,"price":"$0.60738","currency":"USD"},{"qty":2500,"price":"$0.57300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d475582faafb2f5afba0bfa7591518d1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22970YZPT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS22970YZPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS22970YZPT when reusing this data.
