Abstract – This note documents the monolithic power bridge for high-temperature applications implemented within the TERMIS project. This bridge is intended to drive a double-winding Dc brushless motor. The partially depleted 1.0µm-SOI CMOS technology used (X-FAB CI10HS) includes complementary low-voltage MOSFETs, and lateral high-voltage N-channel MOSFETs. The bridge elements (power transistors, synchronization logic, drivers, protections) and the behavior over the 25°C- 225°C temperature range are addressed. The prototype circuit is currently manufactured and measurements will follow
