The high peak current reduces switching losses by charging the gate capacitance quickly, which is critical in high-frequency power supplies and class-D audio amplifiers. The 4 A peak source/sink rating directly governs how fast the external FET's gate capacitance charges and discharges. A 10 nC gate-charge MOSFET transitions in roughly 2.5 ns at 4 A, which keeps the Miller plateau brief and the switching transition efficient. This matters for reducing cross-conduction in half-bridge topologies and for staying inside the FET's safe-operating area during hard-switching events. Designers sizing the bootstrap capacitor or the gate-drive transformer should budget for the full 4 A peak transient — the PDIP package's thermal impedance limits continuous duty, but the peak rating is the headline parameter for selecting this driver over a 2 A or 1 A alternative. If a surface-mount variant is preferred, the same die is available in SOIC-8 (UCC37324D) — a straightforward footprint swap for reflow processes. ## Where it fits in the power train This driver sits between the PWM controller and the power FETs. Typical deployment includes isolated DC-DC converters, uninterruptible power supplies, motor-drive gate-drive boards, and class-D audio output stages. The non-inverting inputs simplify interface logic — one PWM signal per channel drives the corresponding FET directly. The PDIP-8 package suits prototype builds, low-volume production, and repair/rework environments where through-hole mounting is preferred over fine-pitch SMD.","metaTitle":"Texas Instruments UCC37324PE4 Dual 4 A Peak Low-Side Gate","metaDescription":"Texas Instruments UCC37324PE4 dual 4 A peak high-speed low-side gate driver in PDIP-8.

Choose the UCC37324 for active-high PWM inputs (PWM high → FET on) and the UCC37323 for active-low inputs. The pinout differs between the two, so the PCB layout must match the logic polarity."},{"question":"Is UCC37324PE4 compatible with 5V logic?","answer":"Yes, the UCC37324PE4 accepts input logic levels down to 2.7 V, making it directly compatible with 5 V CMOS and TTL logic families. No level-shifting is needed when driven from a 5 V PWM controller or a 3.3 V microcontroller with 5 V-tolerant outputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC37324PE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC37324PE4 when reusing this data.
