Abstract
A solid-state multi-channel protection circuit includes a microcontroller, a current sensor, a plurality of temperature sensors, and first and second multiplexers selectively connecting the current sensor to one of a plurality of solid-state devices and each of the plurality of temperature sensors to the microcontroller. The microcontroller selectively controls the second multiplexer to receive a temperature output associated with one of the plurality of solid-state devices, and selectively controls the first multiplexer to receiver a current output related to the measured current associated with the same solid-state device, wherein the microcontroller provide over-current protection and over-temperature protection based on the received temperature output and the received current output.
