Various applications such as displays, information panels, signs, traffic signals and mobile/portable applications are becoming more and more popular. For these applications, new HB LED drivers with constant current outputs have been designed. The constant LED current guarantees the same brightness for all LEDs and provides a cost advantage in lighting system solutions, as there is no need for external resistors for each individual LED. In addition to their enhanced current accuracy, ST’s HB LED drivers also provide optional features such as embedded power-saving circuitry (ST-patent), as well as built-in LED error detection. Available variants allow designers to specify either or both of these value-added features, in a choice of four industry-standard package options.
