Self-protected, intelligent, power control module

An intelligent, self-protected control module which is a fully protected and configured as a multi-terminal device controlling a number of power field-effect transistors for delivering power to loads. The device can contain a central processing unit or logic, precision Hall-Effect based current sensors for precise measuring of bypass currents, temperature sensors, and input/output circuitry as well as an optional RF receiver. The inputs can incorporate de-bouncing techniques to prevent false turn on/off. Inputs can provide command signals for the processor or logic with built-in watchdog circuitry to monitor the input power supply. The CPU or logic can provide communications with external devices, generate alarms, generate control signals to turn-on/turn-off power MOSFETs, and analyze currents and temperature of each channel. Unlike an electromechanical relay, the present invention is free from arcing and sparking, there are no contact materials to wear, and it is noiseless. The present invention provides over-current protection by shutting down a troubled channel if it is overloaded. It provides protection to the load by limiting the bypass current to the preset value, or shutting the channel off in a case of over-current. The present invention provides over-temperature protection by shutting down an appropriate channel if any of the MOSFET's temperature reaches a predetermined value. The present invention can generate an output signal that is capable of driving an external indicator lamp if a problem has occurred. An optional RF receiver designed to receive a coded signal from a key-chain transmitter can provide a method of enabling the module to accept a control signal from the input remotely.
