Soc power and performance control system

A method comprising:

• determining level of power (P_PSU) input by a power supply unit (PSU) into a charger of a computing system implemented on an SOC;
• determining a current level (IBAT) between the charger and a battery, wherein the battery is configured on the SOC so as to be charged by the charger and to provide power to the charger;
• communicating the P_PSU and the IBAT to a power controller on the SOC;
• determining, based at least in part on the P_PSU and the IBAT that the battery is operating in a plugged-in not charging (PINC) state;
• based at least in part on determining that the battery is operating in the PINC state, adjusting, by the power controller on the SOC, a power supply limit (Psys_LIMIT) by the power controller on the SOC;
• and
• changing the power supplied to one or more components on the SOC based at least in part on the Psys_LIMIT.

A system on chip (SOC), comprising:

• a charger configured to receive power from a power supply unit (PSU);
• a rechargeable battery;
• a PSU power measurement unit configured to determine current level I_PSU output from the PSU and a voltage level Vpsu at the output of the PSU and to communicate the I_PSU and the Vpsu to a power controller on the SOC;
• and
• a battery power measurement unit configured to determine I_BAT output from the rechargeable battery and voltage level Vsys at the output of the battery unit and to communicate the I_BAT and the Vsys to the power controller on the SOC;
• wherein the power controller is configured to:
• determine level of power (P_PSU) input by the PSU into the charger based at least in part on the I_PSU and the Vpsu,
• determine, based at least in part on the P_PSU and the IBAT that the battery is operating in a plugged-in not charging (PINC) state;
• based at least in part on determining that the battery is operating in the PINC state, adjust, by the power controller on the SOC, a power supply limit (Psys_LIMIT) by the power controller on the SOC;
• and
• change the power supplied to one or more components on the SOC based at least in part on the Psys_LIMIT.
