Abstract
The electrical protection circuit disclosed comprises a latchup detection circuit, a threshold detector, an oscillator, a charge pump, a switching circuit, a voltage reference and detection circuit, and a signaling circuit. The latchup detection circuit, the threshold detector, the oscillator, the charge pump, and the switching circuit cooperate to provide latchup protection for the CMOS integrated circuit. The switching circuit provides integrated reverse current protection to the CMOS integrated circuit. The voltage reference and detection circuit, the threshold detector, and the signaling circuit provides low voltage protection for the SRAM-based software-downloaded Field Programmable Gate Array of the CMOS integrated circuit.
