Abstract: A light emission control device controls a first switching element of a light source circuit including a first resistor, a light emitting element, and the first switching element coupled in series between a first power supply node and a second power supply node set to a lower potential than the first power supply node. The light emission control device includes a second detection circuit that compares a first potential difference between both ends of the first resistor with a determination value, a light emission control circuit that outputs a first control signal that controls on/off of the first switching element, and a logic determination circuit that determines whether or not the first switching element is short-circuited. The light emission control circuit sets the first control signal to a first drive stoppage state that inactivates the first control signal, and when the second detection circuit has detected that the first potential difference is larger than the determination value, the logic determination circuit outputs an error signal.

Abstract: A light emission control device includes a detection circuit and a light emission control circuit. The detection circuit detects whether or not a first potential difference across the first resistor is larger than a predetermined value. The light emission control circuit outputs a first control signal for controlling turning on/off of the first switching element and a second control signal for controlling turning on/off of the second switching element. The light emission control circuit sets at least one of the first control signal and the second control signal to a drive stop state to be inactive, when it is detected that the first potential difference is larger than the predetermined value. The light emission control circuit causes a power stop signal to be active, when it is detected that the first potential difference is larger than the predetermined value in the drive stop state.

Abstract: A light emission control device includes a first detection circuit, a second detection circuit, and a light emission control circuit. The first detection circuit detects a first potential difference that is a potential difference between both ends of a first resistor. The second detection circuit detects a second potential difference that is a potential difference between both ends of a second resistor. The light emission control circuit outputs a first control signal for controlling turning on/off of the first switching element and a second control signal for controlling turning on/off of the second switching element. The light emission control circuit performs a stop process of making at least one of the first control signal and the second control signal inactive, when the first potential difference is detected to be smaller than a first threshold value and the second potential difference is detected to be larger than a second threshold value.
