Abstract
A device for current detection is disclosed and includes a protection circuit having a current input provided via a positive input and a negative input arranged in parallel to the positive input, a pair of diodes communicatively coupling the positive input to the negative input, wherein the pair of diodes are configured to protect an operational amplifier from an overvoltage and negative voltages, and a peak detector in communication with the protection stage, wherein the peak detector is configured to receive an output provided by the operation amplifier of the protection stage, and wherein the peak detector is configured to create a peak detector output representative of the current input.
