The 20ns typical rise and fall times keep switching losses low in high-frequency power converters, motor drives, and DC-DC modules. A supply range of 4V to 15V lets it run off a 5V bias or a 12V rail without an extra regulator. ## Inverting input and logic compatibility The input is inverting — a logic high at the input turns the output low, and vice versa. Logic thresholds are set at 1V for VIL and 2V for VIH, which means the driver accepts standard 3.3V and 5V logic levels directly from an MCU or DSP without external level translation. This simplifies the interface in mixed-voltage designs.","metaTitle":"UCC27321DGN MOSFET Driver, 9A Peak, Low-Side, Inverting","metaDescription":"TI UCC27321DGN single low-side MOSFET driver, 9A peak source/sink, 20ns rise/fall, 4V-15V supply, inverting input, -40°C to 105°C, 8-HVSSOP.","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":"Tube","Gate Type":"N-Channel, P-Channel MOSFET","Input Type":"Inverting","Channel Type":"Single","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 15V","Number of Drivers":"1","Base Product Number":"UCC27321","Driven Configuration":"Low-Side","Operating Temperature":"-40°C~105°C(TA)","Rise / Fall Time (Typ)":"20ns, 20ns","Supplier Device Package":"8-HVSSOP","Logic Voltage - VIL, VIH":"1V, 2V","Current - Peak Output (Source, Sink)":"9A, 9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/20b75c5251e8591bc685c5db0fca715d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27321DGN/alternatives.json"},"ai":{"faq":[{"question":"Is UCC27321DGN inverting or non-inverting?","answer":"The UCC27321DGN has an inverting input.
