That peak current capability directly determines how fast the gate of a power MOSFET or IGBT charges and discharges — a 9 A driver can slam a 100 nC gate charge on or off in roughly 11 ns, which keeps switching losses low in a 200–500 kHz converter. ## 20 ns rise and fall — timing budget for the power loop In practice, the actual edge rate depends on the total gate charge of the driven FET and the series gate resistor. The 20 ns figure tells you the internal output stage is fast enough that the external gate resistor — not the driver — will dominate the turn-on dV/dt, which is exactly what you want for controlling EMI and ringing in the power loop. Logic thresholds are 1.1 V (VIL) and 2.7 V (VIH), so a 3.3 V PWM signal from an MCU or DSP will reliably drive the input — no level-shifter needed. The non-inverting input type means the output follows the input polarity, which simplifies the control loop.","metaTitle":"UCC27322DGNR Low-Side Gate Driver, 9A Peak, 20ns Rise/Fall","metaDescription":"Texas Instruments UCC27322DGNR single low-side gate driver, 9A peak source/sink, 20ns typ rise/fall, -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":"Tape & Reel (TR); Cut Tape (CT)","Gate Type":"N-Channel, P-Channel MOSFET","Input Type":"Non-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":"UCC27322","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":"1.1V, 2.7V","Current - Peak Output (Source, Sink)":"9A, 9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/20b75c5251e8591bc685c5db0fca715d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27322DGNR/alternatives.json"},"ai":{"faq":[{"question":"Can UCC27322DGNR be used with a 5V supply?","answer":"Yes, the 4V to 15V supply range includes 5V.
