Abstract
A control chip for power saving is provided. The control chip is configured to operatively receive a first voltage and a first bias voltage. The control chip includes a microcontroller unit and a low power module. The low power module is coupled to the microcontroller unit. The microcontroller unit receives the first voltage to control the operation of at least one component under an operating mode and to stop receiving the first voltage under a power saving mode. The low power module operatively receives the first bias voltage. When the microcontroller unit switches from the operating mode to the power saving mode, the low power module operatively generates a first control signal to cause the microcontroller unit to stop receiving the first voltage. When the low power module detects a trigger signal, the power module operatively generates a second control signal to cause the microcontroller unit to continue receiving the first voltage.
