  • Patent number: 8896370
    Abstract: A voltage regulator bypass circuit to control bypass of a voltage regulator of an integrated circuit device, the voltage regulator bypass circuit including a first voltage detector, a second voltage detector, and circuit. The first voltage detector to detect that a core circuitry voltage level is above a first threshold and to assert a first detect signal at an output in response to the detection. The second voltage detector to detect that an unregulated supply voltage is above a second threshold and to assert a second detect signal at an output in response to the detection. The circuit having a first input coupled to the output of the first voltage detector and a second input coupled to the output of the second voltage detector, the circuit to bypass the voltage regulator in response the output of the latch being cleared.
