Abstract:
Disclosed embodiments include an electronic system with a power on reset (POR) circuit. The POR circuit includes first voltage detection circuitry to perform a first detection on a supply voltage and to output a first control signal in response to the first detection, second voltage detection circuitry to perform a second detection on the supply voltage and to output a second control signal in response to the second detection, and third voltage detection circuitry to perform a third detection on the supply voltage and to output at least one third control signal in response to the third detection. The POR circuit further has sequencing circuitry with a first input to receive the at least one third control signal and to output a reset signal in response to the at least one third control signal.
