CIRCUIT TO AUTOMATICALLY POWER DOWN A CMOS DEVICE WHICH IS LATCHED UP

摘要

An integrated circuit protection device for resetting an integrated circuit when latch-up occurs. A switching means is connected in series with a current path to selectively control the flow of current through an integrated circuit. A voltage comparison means monitors changes in voltage which correspond to change in the currant flowing through the integrated circuit. The voltage comparison means operates cooperatively with a storage means to provide an output to control the switching switching means causes it to restrict current flow through the integrated circuit.
