The inverting input means the output goes high when the input is pulled low — a detail that matters when pairing with a PWM controller that expects active-low drive. ## Switching speed and drive strength The 4A peak current handles the gate charge of a moderate-sized IGBT or MOSFET — think 10 nC to 30 nC gates — without excessive crossover conduction loss. Supply voltage tolerance from 4.5V to 18V covers the common automotive rails: 5V logic bias, 12V battery, and intermediate bus voltages. The low-side configuration means the driver's output references the same ground as the control logic — no level-shifting complexity. The base product number UCC27518 identifies the family; the Q1 suffix flags the automotive qualification.","metaTitle":"UCC27518AQDBVRQ1 Automotive Low-Side Gate Driver, 4A Peak","metaDescription":"Texas Instruments UCC27518AQDBVRQ1 single-channel low-side gate driver, AEC-Q100 qualified. 4A peak source/sink, 4.5V-18V supply, 8ns rise time.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Gate Type":"IGBT, N-Channel MOSFET","Input Type":"Inverting","Channel Type":"Single","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 18V","Number of Drivers":"1","Base Product Number":"UCC27518","Driven Configuration":"Low-Side","Operating Temperature":"-40°C~150°C(TJ)","Rise / Fall Time (Typ)":"8ns, 7ns","Supplier Device Package":"SOT-23-5","Logic Voltage - VIL, VIH":"-","Current - Peak Output (Source, Sink)":"4A, 4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5205","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c8fee81c931e4e6d8a7dd0b2bf55e64.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27518AQDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is UCC27518AQDBVRQ1 automotive grade?","answer":"Yes.
