ABSTRACT:
A monitoring and protection circuit associated with a voltage regulator supplying power to a CMOS device can sense over current levels precisely enough for determining if a fault has occurred in a circuit of the CMOS device, e.g., latch-up, failed or shorted transistor, etc., then this monitoring and protection circuit may automatically generate a fault alert signal and/or cycle power to the CMOS device when an unexpected over current may occur, e.g., CMOS circuit latch-up. The monitoring and protection circuit may be integrated with a voltage regulator, e.g., low drop-out (LDO) voltage regulator on a single integrated circuit substrate. The monitoring and protection circuit and voltage regulator may be fabricated with a CMOS device, e.g., digital processor on a single integrated circuit substrate.
