That current rating is the key spec for driving the gate capacitance of large N-channel or P-channel MOSFETs: a 4 A peak can charge a 10 nC gate in roughly 2.5 ns, though the 20 ns rise time sets the practical floor. The driver operates from a 4 V to 15 V supply rail, which covers the standard bias voltages for 5 V and 12 V gate drives used in synchronous rectifiers, buck converters, and push-pull stages. Both channels are independent with inverting inputs, meaning the output goes high when the input is low. This simplifies the interface with controllers that deliver a complement signal, and the two channels can be staggered for interleaved or half-bridge topologies without external logic. ## Low-side only — no bootstrap, no floating supply The driven configuration is low-side, so the source of the external MOSFET connects to ground (or the negative rail). For a half-bridge the high-side MOSFET needs a bootstrap or isolated supply; the UCC27423P drives the low-side FET directly. The gate type covers both N-channel and P-channel MOSFETs, so it can handle a P-channel high-side if the source is connected to the positive rail (then the driver's ground is the source node, which is not the system ground — verify the common-mode range). The inverting input logic means a low input turns the output on — plan the controller's output polarity accordingly. The independent channel type allows one channel to be used for a primary switch and the second for an active clamp or synchronous rectifier, with separate timing control. ## Package and temperature grade — through-hole, wide range Housed in an 8-PDIP (0.300\", 7.62 mm) through-hole package, the UCC27423P is suited for prototyping, rework-friendly designs, and low-volume production where a socket is preferred. TI lists the UCC27423P as Active. The base product number UCC27423 indicates the family includes variants with non-inverting inputs (UCC27424) and dual-input (UCC27425) — if your prototype needs the opposite polarity, the leadframe and footprint are the same across the 8-pin DIP package, making a drop-in swap possible without a board change.","metaTitle":"UCC27423P Dual 4A Low-Side MOSFET Driver, 8-PDIP","metaDescription":"Texas Instruments UCC27423P dual low-side MOSFET driver, 4A peak output per channel, 4V–15V supply, 20ns rise/15ns fall, -40°C to 125°C, 8-PDIP.","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":"Independent","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 15V","Number of Drivers":"2","Base Product Number":"UCC27423","Driven Configuration":"Low-Side","Operating Temperature":"-40°C~125°C(TA)","Rise / Fall Time (Typ)":"20ns, 15ns","Supplier Device Package":"8-PDIP","Logic Voltage - VIL, VIH":"1V, 2V","Current - Peak Output (Source, Sink)":"4A, 4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9386","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/147562a5d4d0f99c835f72b18e2ae79c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27423P/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to UCC27423P?","answer":"Within the UCC2742x family, the UCC27424P (non-inverting inputs) and UCC27425P (one inverting, one non-inverting) share the same 8-PDIP footprint and pinout.
