A current trip point detection circuit includes a transistor, a series of resistors, an amplifier, a comparator, and a series of switching circuits. The first transistor and the resistors are configured as an inverting gain stage. The amplifier cooperates with the first transistor to operate in a negative feedback arrangement. The gain in the feedback loop is adjusted by selective activation of additional transistors, where each additional transistor lowers the overall loop gain. The comparator is selectively coupled to a tap point in a voltage divider that is formed by resistors. The voltage divider tap point is selected to set a threshold for detection. The trip point is detected by the comparator, and may be adjusted between high and low trip points through the various configurations of the gain and voltage divider tap points via the switching circuits.
