ABSTRACT:
A latch-up protector, and an associated method, for an electronic circuit powered by both a fixed power supply and a pumped power supply. Operation of the latch-up protector prevents the occurrence of latch-up of the circuit during powering-up of the circuit. During powering-up of the electronic circuit, the latch-up protector prevents the application of an input signal to the electronic circuit which might instigate the occurrence of latch-up until the pumped power supply reaches a selected voltage level.
