Abstract
A method, apparatus, and device provide for the detection of insufficient supplied power supplied to a device. A current multiplier of the device, operable as a voltage regulator, is coupled to the power source, receives a clock signal, and generates a control signal. A digital counter, clocked by the clock signal and reset by the control signal, generates an overflow output in response to an overflow condition of the digital counter that indicates that the current sourcing capability of the power source has fallen below a current threshold of the device. A compensatory response by the device in response to the detection of insufficient supplied power may be provided as well.
