Driver for led matrix

Description. The STLED is a 5x24 dot matrix LED display driver. It can drive each dot with a current up to 20 mA. Rows of the matrix are multiplexed. Each LED in a row is driven by a separate low-side current mirror. Current regulators are . The LED Segment and Matrix Driver component is a multiplexed LED driver that can handle up to 24 segment signals and 8 common signals. It can be used to drive 24 7-segment LEDs, eight 14/segment LEDs, eight RGB 7-segment LEDs, or a . To drive a multiplexed LED matrix, high side drivers and low side drivers both are required, as the current requirements are high and cannot be met by the microcontrollers. To have an average current of suppose 10mA through the LEDs, if we use row multiplexing we would need a peak current of mA through each LED for this particular board (to switch on all LEDs - thus a Estimated Reading Time: 3 mins.

Description. The STLED is a 5x24 dot matrix LED display driver. It can drive each dot with a current up to 20 mA. Rows of the matrix are multiplexed. Each LED in a row is driven by a separate low-side current mirror. Current regulators are supplied by an integrated boost DC-DC converter. LED matrix drivers are monolithic high-efficiency LED drivers designed to supply LED arrays used in the backlighting of LCD panels in consumer, industrial and automotive applications. Housed in compact QFN packages, these ICs integrate a power converter section and a LED array driver section consisting of several PWM-dimmable current generators. The wide input voltage range covers the most common voltage buses (5 V, 12 V and 24 V). To drive a multiplexed LED matrix, high side drivers and low side drivers both are required, as the current requirements are high and cannot be met by the microcontrollers. To have an average current of suppose 10mA through the LEDs, if we use row multiplexing we would need a peak current of mA through each LED for this particular board (to switch on all LEDs - thus a total of 8*3=24 rows).
