Description
CONAN IC has been designed in the framework of ARTES ESA program by a consortium composed of Airbus Defence and Space, which has specified the requirement for this electronic circuit breaker, and Weeroc which has designed the CONAN IC. Telecom Satellite Power Control and Distribution Units (PCDUs) in particular and most satellite PCDUs in general still use fuses as circuit breaker. Having a programmable electronic circuit breaker controller device featuring double isolation, redundancy, telemetry and latch-up current limitation will be a game changer for PCDUs circuit breaking. CONAN is a dual power P-channel MOSFET controller IC (nominal and redundant) designed in XFAB XT018 technology. It embeds all these features over a 20 V to 136 V voltage span and a 0.5 A to 12.5 A current limitation span. CONAN features a nominal and redundant space serial bus communication line allowing the TM/TC of 254 CONAN on the same bus line. CONAN embeds 8-heater drivers and 8-heater status on top of the circuit breaking capability. CONAN complete features and architecture will be presented in this paper along with simulation and measurement results.
