That symmetry simplifies dead-time budgeting because the turn-on and turn-off delays match closely when driving the same capacitance. Rise time is 20ns typ, fall time 15ns typ. The 5ns asymmetry is small enough that most designs can treat them as equal for first-order loss calculations, but the faster fall helps ensure the MOSFET turns off before the complementary device turns on. ## Supply range and gate-type flexibility Supply voltage spans 4V to 15V, covering the common 5V and 12V rails used in industrial power stages. At 5V the driver still delivers full 4A peak; the output swing is rail-to-rail, so a 5V supply limits the gate drive to 5V — fine for logic-level MOSFETs but insufficient for standard 10V-threshold devices. Unlike most low-side drivers that only handle N-channel MOSFETs, this part also drives P-channel MOSFETs. That makes it useful for load switches or high-side drivers where the P-channel is ground-referenced through a bootstrap or charge pump. Input logic thresholds are 1V (VIL) and 2V (VIH), compatible with 3.3V and 5V logic families without level shifting. Both inverting and non-inverting inputs are available, so one driver channel can be configured as a buffer and the other as an inverter from a single PWM source.","metaTitle":"UCC27425DR – Texas Instruments Low-Side Gate Driver, 4A Peak","metaDescription":"UCC27425DR from TI: dual low-side gate driver, 4A source/sink peak, 20ns/15ns rise/fall, drives N/P-channel MOSFETs.

The datasheet specifies gate type as N-Channel, P-Channel MOSFET. The driver's output stage is a totem-pole that swings rail-to-rail, so it can drive a P-channel MOSFET's gate to the supply rail to turn it off, and to ground to turn it on. Confirm the P-channel's Vgs(th) is within the supply range."},{"question":"What is the difference between UCC27425DR and UCC27424DR?","answer":"The UCC27424DR has the same pinout and package but offers 4A peak output current with a different input logic scheme — the UCC27424 uses dual inverting inputs, while the UCC27425 provides one inverting and one non-inverting input per channel. The supply range, rise/fall times, and temperature grade are identical."},{"question":"Can UCC27425DR be used as a replacement for UCC27424?","answer":"Yes, if the input logic polarity matches your circuit. The UCC27425 has one inverting and one non-inverting input per channel, while the UCC27424 has two inverting inputs. If your design expects a non-inverting drive on one channel, the UCC27425 is a direct drop-in. If both channels need inverting inputs, you can invert the PWM signal externally or use the UCC27424."},{"question":"When sourcing UCC27425DR, what is the closest functional second-source — LM5106MM/NOPB?","answer":"The LM5106MM/NOPB is a half-bridge driver with a bootstrap diode for the high-side N-channel, not a dual low-side driver. It drives only N-channel MOSFETs and has a 1.2A peak output versus the UCC27425's 4A symmetric drive. The LM5106 is not a pin-compatible second-source; it serves a different topology (half-bridge vs dual low-side). For a low-side replacement, look at the UCC27424 or UCC27423 family from TI."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC27425DR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC27425DR when reusing this data.
