Optical sensor module and power control method thereof

An electronic device comprising an optical sensor module and a light source driver,

• the optical sensor module comprising:
• one or more light-emitting elements;
• one or more light-receiving elements;
• a signal processing circuit configured to control driving of the light emitting elements and the one or more light-receiving elements;
• and
• at least one processor,
• the light source driver being configured to control power supply of the at least one light-emitting element,
• wherein the signal processing circuit is configured to, when the optical sensor module is driven, under a control of the at least one processor, configure a control signal of the light source driver in response to a light source of the one or more light-emitting elements and a turn-on/off timing signal of the one or more light-emitting elements according to a sensor measurement mode or a measurement function,
• wherein the signal processing circuit is configured to, based on the control signal, apply an output voltage obtained by boosting an input voltage through the light source driver as power of the one or more light-emitting elements in turn-on period of the one or more light-emitting elements,
• wherein the signal processing circuit is configured to block the power of the one or more light-emitting elements by limiting output of the light source driver in turn-off period of the one or more light-emitting elements, and
• wherein the signal processing circuit is configured to transmit a signal collected based on the one or more light-receiving elements to the at least one processor.
