That 5A figure is the current the driver can deliver into the gate capacitance during the switching transition — it determines how fast the external IGBT or N-Channel MOSFET turns on and off. With a 7 ns typical rise time and 6 ns fall time, this part keeps switching losses low in a 100 kHz+ power stage, but the fast edges demand a tight layout: the gate-drive loop (driver output → gate resistor → gate-source → source return) needs to be under 1 cm to avoid voltage overshoot on the gate. ## Supply range and temperature — where it survives The supply range spans 4.5 V to 18 V, so the same driver works on a 5 V logic rail or a 12 V gate-drive bus. The junction temperature rating goes to 140°C — that is the die temperature, not the ambient. In a motor-drive enclosure or an under-hood ECU where the ambient hits 105°C, the 140°C TJ ceiling gives enough headroom for self-heating from the 5A peaks. ## Two independent channels — layout flexibility The two driver channels are independent, each with its own inverting and non-inverting inputs. That means one channel can drive a high-side bootstrap configuration while the other drives the low-side device, or both channels can be paralleled for higher peak current into a single large IGBT gate. The independent input structure also lets you use one channel as a shoot-through protection interlock by cross-coupling the inputs — a common trick in half-bridge designs.","metaTitle":"UCC27527DSDR gate driver, 5A peak, 4.5-18V, 8-SON","metaDescription":"Texas Instruments UCC27527DSDR dual low-side gate driver for IGBT and MOSFET. 5A peak source/sink, 7/6 ns rise/fall, -40°C to 140°C.","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":"IGBT, N-Channel MOSFET","Input Type":"Inverting, Non-Inverting","Channel Type":"Independent","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 18V","Number of Drivers":"2","Base Product Number":"UCC27527","Driven Configuration":"Low-Side","Operating Temperature":"-40°C~140°C(TJ)","Rise / Fall Time (Typ)":"7ns, 6ns","Supplier Device Package":"8-SON (3x3)","Logic Voltage - VIL, VIH":"-","Current - Peak Output (Source, Sink)":"5A, 5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0650","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/307ec5c4980ffba75cd9b497083b2071.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27527DSDR/alternatives.json"},"ai":{"faq":[{"question":"Is UCC27527DSDR compatible with IGBTs?","answer":"Yes, the gate type is specified for both IGBT and N-Channel MOSFET.
