That 4A rating means it can slam the gate of a 10 nC MOSFET on in about 2.5 ns (theoretically) — in practice, the 20 ns typical rise time and 15 ns fall time set the real edge rate. For a 12V gate-drive rail, the 4.5V to 15V supply range covers the common bias voltages used in industrial and telecom power supplies. ## Inverting inputs and independent channels Both channels are inverting — a logic high on the input turns the output low, and vice versa. The two channels are independent, so you can drive two separate MOSFETs with different duty cycles or phase shifts, or parallel them for higher peak current into a single gate. The logic thresholds are 1V VIL and 2V VIH, compatible with 3.3V and 5V logic families without level shifting. ## Military temperature range — not just a datasheet number Rated for junction temperature from -55°C to 150°C, this driver is specified for the full military temperature envelope. The 8-SOIC package is standard surface-mount, so it fits on a four-layer board with a thermal pad pour under the body. TI lists the UCC27323DR as Active.","metaTitle":"UCC27323DR Low-Side MOSFET Driver, 4A Peak, 8-SOIC","metaDescription":"Texas Instruments UCC27323DR dual low-side MOSFET driver with 4A peak output, 20ns/15ns rise/fall, -55°C to 150°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)","Gate Type":"N-Channel, P-Channel MOSFET","Input Type":"Inverting","Channel Type":"Independent","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 15V","Number of Drivers":"2","Base Product Number":"UCC27323","Driven Configuration":"Low-Side","Operating Temperature":"-55°C~150°C(TJ)","Rise / Fall Time (Typ)":"20ns, 15ns","Supplier Device Package":"8-SOIC","Logic Voltage - VIL, VIH":"1V, 2V","Current - Peak Output (Source, Sink)":"4A, 4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/101e32c5d1690d460d938a52f40579f4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27323DR/alternatives.json"},"ai":{"faq":[{"question":"Is UCC27323DR equivalent to UCC27324DR?","answer":"UCC27323DR and UCC27324DR are both dual low-side drivers with the same 4A peak drive and same package, but the input logic is inverted on the UCC27323DR (inverting) versus non-inverting on the UCC27324DR.

The 4.5V to 15V supply range covers the 10V to 12V gate-drive levels typical for standard-logic-level and standard-threshold MOSFETs.
