Abstract

See full text

A short detection circuit includes a first transistor, a switched load circuit, a second transistor, a switched capacitor circuit, and a comparator. The first transistor is configured to conduct a load current. The switched load circuit is coupled to the first transistor. The switched load circuit is configured to switchably draw a test current. The second transistor is coupled to the first transistor. The second transistor is configured to conduct a sense current. The sense current includes first and second portions that are respectively representative of the load current and the test current. The switched capacitor circuit is coupled to the second transistor. The switched capacitor circuit is configured to generate a short detection voltage representative of the second portion. The comparator has a first comparator input coupled to the switched capacitor circuit. The comparator is configured to compare the short detection voltage to a short threshold voltage.
