Abstract
A control circuit for an electronic circuit is disclosed. The electronic circuit includes a light-emitting element and control pin. The light-emitting element is coupled to the control pin. The control circuit includes a driving circuit and at least one detection circuit. The driving circuit is coupled to the control pin. The driving circuit drives the light-emitting element during a light-emitting period in a driving cycle of the light-emitting element. Each of the at least one detection circuit is coupled to the control pin. The at least one detection circuit receives a voltage value at the control pin during at least one non-light-emitting period in the driving cycle, and provides at least one detection result according to the voltage value of the control pin. The light-emitting element emits light during the light-emitting period and stops emitting light during the at least one non-light-emitting period.
