Control circuit for electronic circuit

A control circuit for an electronic circuit, wherein the electronic circuit comprises a light-emitting element and a control pin, wherein the light-emitting element is coupled to the control pin, wherein the control circuit comprises:

• a driving circuit, coupled to the control pin, configured to drive the light-emitting element during a light-emitting period in a driving cycle of the light-emitting element;
• and
• at least one detection circuit, each coupled to the control pin, configured to receive a voltage value at the control pin during at least one non-light-emitting period in the driving cycle, and provide at least one detection result according to the voltage value of the control pin,
• wherein the light-emitting element emits light during the light-emitting period and stops emitting light during the at least one non-light-emitting period,
• wherein the electronic circuit further comprises a thermistor and a sensing resistor,
• wherein the light-emitting element is coupled between the control pin and a connection node,
• wherein the thermistor is coupled between the control pin and the connection node,
• wherein the sensing resistor is coupled between the connection node and a reference low voltage, and
• wherein the at least one detection circuit comprises:
• a first detection circuit, coupled to the control pin, configured to generate a temperature detection signal according to a resistance value of the thermistor during a first non-light-emitting period in the driving cycle;
• and
• a second detection circuit, coupled to the control pin, configured to detect a current value flowing through the sensing resistor during a second non-light-emitting period in the driving cycle.
