About the Iso7741 gate drive fixture PCB

Iso7741 gate drive fixture is an open source PCB design by BennetLeff, published on GitHub under the Custom license license. It is a 2-layer board measuring 100 × 80 mm, with 4 components from 2 distinct parts.

Other key parts include the ISO7741FQDWWRQ1 and UCC27517AQDBVRQ1.

From the project

a breville control freak ++

Temper is a consumer induction cooker built around three pillars: an ESP32-S3 firmware with an 8-state transition-table machine handling real-time power control and hardware-latched protection circuits; a KiCad PCB design optimized through a custom CP-SAT-based signal-integrity and thermal-aware placer pipeline; and a Python/Rust placer toolchain (CP-SAT solver, geometry/DRC/DSN/IPC crates, workflow DAG) that automates layout and checks placement against IPC standards. Protection — over-current, over-voltage, thermal shutdown, UVLO — is designed to be hardware-latched with firmware monitoring.
