1. A powerline load monitor, comprising:
a voltage sense input coupled with an input of a first analog-to-digital converter (a first ADC);
a first current sense input coupled with an input of a second ADC;
a serial interface with two or more outgoing data inputs, wherein a first of the two or more outgoing data inputs is coupled with an output of the first ADC, and a second of the two or more outgoing data inputs is coupled with an output of the second ADC;
a power manager with a clock input, a supply input, and a standby output coupled with at least one of the first ADC, the second ADC, or the serial interface; and
a clock input coupled with a clock input of the serial interface and with the power manager clock input;
wherein:
upon receiving a first clock pulse, the power manager puts the powerline load monitor in an active mode and trigger a first timer with a first timeout time, the first ADC converts a sensed voltage to a first digital value, and the second ADC converts a sensed current to a second digital value; and the serial interface outputs a data bit of a digital value of one of the two or more outgoing data inputs;
upon receiving additional clock pulses, the power manager triggers the first timer;
upon receiving additional clock pulses, the serial interface outputs additional data bits; and
a first timeout time after receiving a most recent clock pulse on the clock input, the power manager puts the powerline load monitor into a standby mode.
