Abstract
A configurable light source driver device includes circuitry that detects the presence of a resistor when connected to a terminal of the device and automatically configures the device to operate as a differential driver circuit with low EMI emission and a level of circuit stability that is selected on the basis of parasitic impedance conditions of the differential driver circuit. When the terminal is left unconnected, the configurable light source driver device automatically configures itself to operate as a single ended driver circuit with low power consumption and a different level of circuit stability that is selected on the basis of parasitic impedance conditions of the single ended driver circuit. Furthermore, the configurable light source driver device can include a pulse width adjustment circuit for modifying certain operating characteristics of each of the differential driver circuit and the single ended driver circuit.
