Job Description

  • Principal Architect - Isolated Gate Driver IC

  • Areas of Responsibilities
  • Lead architecture and design definition for isolated gate driver ICs used with SiC and GaN power switches, optimized for high switching speed, high CMTI, and robustness.
  • Architect complete driver solutions including:
  • High/low side output stages (with Miller clamp, active pull-up/down, configurable source/sink)
  • Isolation interface (capacitive, magnetic, or optical)
  • Integrated protections (UVLO, DESAT, SCP, soft turn-off, active clamp)
  • Diagnostic and telemetry features (SPI/IC interface, status flags)
  • Define system-level integration strategy for energy platforms, ensuring reliable performance across wide operating voltages, temperatures, and transient conditions.
  • Ensure design meets isolation standards (UL1577, VDE0884, IEC 60747-17) and supports high CMTI ( 100 kV/s) performance.
  • Collaborate with SiC/GaN FET designers, power module architects, and system teams to define drive strength, layout constraints, and thermal performance targets.
  • Guide the team on HV layout practices, creepage/clearance, EMI reduction, and packaging co-design.
  • Drive IP reuse, design scalability, and enable the gate driver IP to be leveraged across energy, automotive, and industrial portfolios.
  • Lead architecture reviews, mentoring, and documentation of system specifications and design decisions.
  • Contribute to long-term roadmap and technology strategy for wide-bandgap driver solutions across all business units

Technical Skills:

  • Expert in gate driver circuit design for wide-bandgap devices (SiC MOSFETs, GaN HEMTs).
  • Strong understanding of:
  • Level shifters, push-pull buffers, active clamps, and short-circuit protection
  • Isolation technologies and barrier design (capacitive/magnetic/optical)
  • High-side/low-side driver pairing and bootstrap techniques
  • Experience with protection and diagnostics: UVLO, DESAT, OCP, OTP, and integrated fault reporting.
  • Knowledge of high-voltage ( 600 V) and high-frequency ( 100 kHz-1 MHz) design constraints.
  • Tools: Cadence Virtuoso, Spectre, MATLAB, and simulation tools (e.g., PLECS, ADS, LTspice).
  • System-level co-design experience with SiC/GaN switches, power modules, and packaged solutions.
Strong foundation in EMI/EMC, thermal behavior, and safe operating area (SOA) management
