Power delivery circuit with current detection

摘要: A power delivery circuit for supplying load current to a includes switch connected on the high potential side of load. In order detect condition, such as an over-current condition in load, sensing and detection preferably cooperates with wherein comprises multicellular device plurality terminals. Such terminals include first main terminal source potential, second connecting majority cells auxiliary at one end minority so provide generally proportional current, cells. The branch between ground including, serial circuit, current-to-voltage converting resistor providing voltage approximately bias signal-controlled transimpedance device, another signal branch.
