A load current is limited to a safe level with a current protection logic circuit within a first selected interval after detection of a fault condition. The current protection logic circuit returns the load current to a normal level within a second selected interval after correction of the fault condition, wherein said safe level is less than one half of the normal level. The current protection logic circuit is a feature of a high side driver comprising at least two source drivers, each source driver being configured to switch an electrical load to a common power supply, and comprising a respective current protection logic circuit.

A geosynchronous satellite control and telemetry communication system has branch modules distributed throughout the satellite which serially interface clusters of control and/or analog nodes to the central command and data handling processor. Each branch module is connected to the central command and data handling processor by serial data channels. The branch modules are physically located close to the control/telemetry nodes for which they serve as interfaces to the central command and data handling processor and where appropriate are integrated into the satellite subsystems themselves.
