That drive strength handles the gate charge of large TO-247 or TO-220 N-channel and P-channel MOSFETs without slowing down the switching edge. ## Supply and logic — no level shifter needed Supply range is 4 V to 15 V, covering both 5 V logic rails and 12 V gate-drive bias from a single supply. The input is inverting: a logic high on the input pulls the gate output low, and vice versa. That matters when the upstream controller's PWM polarity is fixed and you need to invert the drive signal without an extra logic gate. ## Temperature range and package — board-fit notes The 8-PDIP package is through-hole, which simplifies prototyping and rework. It also gives better thermal conduction to the board than a small-outline package — the copper traces and pads under the DIP body sink heat from the die during repetitive switching.","metaTitle":"UCC27321PG4 Texas Instruments Gate Driver, 9 A Peak","metaDescription":"TI UCC27321PG4 single low-side gate driver with 9 A peak source/sink, 20 ns rise/fall, 4 V to 15 V supply.

A logic high on the input pulls the gate output low, and a logic low pulls the output high. If you need a non-inverting version, look at the UCC27322 (same pinout, non-inverting input)."},{"question":"Does UCC27321PG4 work with N-channel MOSFETs?","answer":"Yes — the UCC27321PG4 drives both N-channel and P-channel MOSFETs. For a low-side N-channel, connect the driver output to the gate and the source to ground; the 9 A peak current charges the gate capacitance quickly, keeping switching losses low."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC27321PG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC27321PG4 when reusing this data.
