Voltage detector with high voltage protection

A system comprising:

• a memory;
• a wireless interface;
• and
• a processor, coupled to the memory, and operable to communicate with other devices using the wireless interface, the processor including an in-field programmable fuse array and an apparatus which comprises:
• a voltage level detector to monitor a first power supply node for protecting the apparatus against over-voltage and under-voltage power supply conditions, wherein the voltage level detector asserts an over-voltage signal when the voltage of the first power supply node exceeds an over-voltage threshold, and the voltage level detector asserts an under-voltage signal when the voltage of the first power supply node falls below an under-voltage threshold;
• 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,
• wherein the voltage level detector comprises a first comparator with a first input coupled to a first terminal between a first stack of devices and a first resistor, and a second input coupled to a second terminal between a second stack of devices and a second resistor, wherein the first resistor is coupled to ground and the first stack of devices, and wherein the first stack of devices is coupled to the first power supply node.
