摘要: A driver is able to drive an analog interface module or a digital interface module, for example an LED module. A set of output pins is for connection to the module, with the same set of output pins used for an analog interface LED module as for a digital interface LED module. A detecting circuit detects whether the module is an analog module or a digital module, based on a signal at a control pin. The configuration of the driver is then set accordingly using an analog drive signal or using a digital communication interface for the LED module parameter collection. The driver further comprises a first switching circuit (20) for switching a supply voltage (V) to the power supply pin (VCC), and a second switching circuit (30) for coupling a supply voltage (V) to the control pin through a resistor (R6), wherein the detecting circuit (16) is configured to determine that the module is digital when the first switching circuit (20) supplies the supply voltage (V) to the power supply pin and the second switching circuit (30) isolates the supply voltage (V) from the control pin.
