Performing a power cycle reset in response to a change in charging power applied to an electronic device

A method comprising:

• providing, by a charging circuit, a voltage to a control circuit based on a change in power provided to the charging circuit, wherein the charging circuit is configured to charge an energy storage device configured to power a load via a power supply circuit, wherein the power supply circuit is configured to selectively couple the load to (i) a power supply path through which the power supply circuit uses the energy storage device to power the load and (ii) a discharge path that discharges the load, wherein the control circuit comprises (i) a switch and (ii) one or more passive circuit elements coupled to the switch, wherein the charging circuit providing the voltage to the control circuit produces a time-varying voltage at the switch for a period of time that places the switch in a high-conductance state during an initial portion of the period of time and a low-conductance state during a subsequent portion of the period of time, wherein a duration of the initial portion of the period of time is controlled at least in part by a resistance and a capacitance of the one or more passive circuit elements;
• applying, by the control circuit, a control signal to the power supply circuit for the period of time;
• in response to the control circuit applying the control signal, the power supply circuit coupling the load to the discharge path so as to discharge the load during the period of time;
• following the period of time, the control circuit ceasing to apply the control signal to the power supply circuit;
• and
• in response to the control circuit ceasing to apply the control signal, the power supply circuit coupling the load to the power supply path.

An electronic device comprising:

• a power supply circuit;
• an energy storage device configured to power a load via the power supply circuit, wherein the power supply circuit is configured to selectively couple the load to (i) a power supply path through which the power supply circuit uses the energy storage device to power the load and (ii) a discharge path that discharges the load;
• a charging circuit, wherein the charging circuit is configured to charge the energy storage device with power applied to the charging circuit from a power source;
• and
• a control circuit comprising:
• a switch;
• a first set of one or more passive circuit elements coupled to the switch;

• a second set of one or more passive circuit elements coupled to the switch;
• wherein the control circuit is configured to:
• (i) receive an indication of a change in power provided to the charging circuit, (ii) in response to receiving the indication from the charging circuit, apply a control signal to the power supply circuit for a period of time, wherein the period of time is controlled at least in part by a first capacitance of the first set of one or more passive circuit elements and a second capacitance of the second set of one or more passive circuit elements, wherein the power supply circuit is configured to, in response to the control circuit applying the control signal, couple the load to the discharge path so as to discharge the load during the period of time, and (iii) following the period of time, cease to apply the control signal to the power supply circuit, wherein the power supply circuit is configured to, in response to the control circuit ceasing to apply the control signal, couple the load to the power supply path.
