At 1.5 A continuous output, that resistance drops about 134 mV and dissipates roughly 200 mW — well within the SC-70-6 package's thermal budget at 25°C ambient, but worth checking against your load current and ambient temperature. The part operates from 1.6 V to 5.5 V on the load side and does not require a separate Vcc/Vdd bias supply, which simplifies the rail design for point-of-load switching in mixed-voltage systems. ## Slew rate and load discharge — why they matter on a power-good sequence The slew-rate controlled turn-on limits inrush current into downstream capacitive loads, which prevents the upstream regulator from drooping or hiccupping during power-up. The load discharge feature pulls the output to ground through an internal resistor when the switch is disabled — no floating output rail that could leave a downstream IC in an undefined state. Both features are integrated; no external pull-down or soft-start capacitor needed. ## Short-circuit protection without the external sense resistor Fault protection is built in: the TPS22919DCKT includes short-circuit protection that limits the output current during a fault event. The 105°C ceiling gives headroom above the 85°C industrial standard for self-heating at the 1.5 A maximum output.","metaTitle":"TPS22919DCKT load switch, 1.5 A, 89 mOhm, SC-70-6","metaDescription":"TI TPS22919DCKT high-side load switch: 1.6 V to 5.5 V input, 1.5 A output, 89 mOhm Rds(on), load discharge, SC-70-6.","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":"Load Discharge, Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"89mOhm","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","Product Status":"Active","Voltage - Load":"1.6V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"Short Circuit","Number of Outputs":"1","Base Product Number":"TPS22919","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~105°C","Current - Output (Max)":"1.5A","Supplier Device Package":"SC-70-6","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f5ac5ef2c5f1a37c69f52afaef9d0906.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22919DCKT/alternatives.json"},"ai":{"faq":[{"question":"What is the typical Rds(on) for TPS22919DCKT?","answer":"Typical on-resistance is 89 mOhm.
