Abstract
A power control circuit for replacing a current limiting fuse in an electrical protection circuit or for switching large currents rapidly has an array of transistors, each having an identical characteristic to each other and to a device under test, to provide parallel current paths. All of the rows of the transistor array are biased 'on' except for a predetermined row. A gate signal is generated to control the 'on/off' state of the transistors in the predetermined row, the gate signal being a function of the presence of excessive current--holding the predetermined row of transistors biased 'on' in normal operation, and turning the predetermined row of transistors 'off' when excessive current is detected.
