Abstract
Described is an apparatus comprising: a voltage level detector to monitor a first power supply node; and a voltage level protector, coupled to the voltage level detector, to protect the voltage level detector from receiving a power supply on the first power supply node above a pre-defined threshold voltage. Described is also a voltage level protector to protect a first power supply node from receiving a power supply above a pre-defined threshold voltage, the voltage level protector comprising: a first p-type device coupled to a second power supply node, the second power supply node to receive a power supply higher than the power supply on the first power supply node; and a second p-type device coupled in series to the first p-type device, the second p-type further coupled to the first power supply node, which is for coupling to a voltage level detector.
