  • Publication number: 20250089140
    Abstract: An LED driving apparatus, a microcontroller, and a control method for an LED module are provided. The LED driving apparatus includes a power supply module, a switch module, and a control module. The power supply module is configured to supply power to the LED module, in which the power supply module determines whether to trigger an overcurrent protection based on whether an output current exceeds a threshold current. The control module is configured to receive an overcurrent detection signal to control a conduction state of the switch module, so as to affect the current amount of the LED module. When the overcurrent detection signal indicates the output current exceeds the threshold current, the control module outputs a first control signal based on the overcurrent detection signal to control the switch module, to prevent the overcurrent protection from being triggered.
