POWER SAFETY CIRCUIT, INTEGRATED CIRCUIT DEVICE AND SAFETY CRITICAL SYSTEM |
摘要 |
A power safety circuit comprises a power sense terminal; an output terminal; an output driver unit connected to the output terminal; an input terminal connectable to receive a first power from a power source and arranged to supply the first power to the output driver unit; and a power detection unit arranged to detect a state of the input terminal and provide a power sense signal to the power sense terminal; wherein the power sense terminal is arranged to supply a second power to the output driver unit when the power sense signal indicates a level of the first power below a minimum level for driving the output terminal. An integrated circuit device comprises at least one power safety circuit. A safety critical system comprises at least one integrated circuit device with at least one power safety circuit. |
