| abstract | PROBLEM TO BE SOLVED: To provide a light emission control device or the like capable of appropriately dealing with an overcurrent based on two current detection results. A light emission control device 100 includes a first detection circuit 131, a second detection circuit 132, and a light emission control circuit 101. The first detection circuit 131 detects the first potential difference, which is the potential difference between both ends of the first resistor RCS. The second detection circuit 132 detects the second potential difference, which is the potential difference between both ends of the second resistor RIS. The light emission control circuit 101 outputs a first control signal DRV that controls the on / off of the first switching element 11 and a second control signal GTB that controls the on / off of the second switching element 12. The light emission control circuit 101 detects that the first potential difference is smaller than the first threshold value and that the second potential difference is larger than the second threshold value, the first control signal DRV and the second control signal GTB. Performs a stop process that deactivates at least one of the above. [Selection diagram] Fig. 1 |
