STLED524 General Description

The STLED524 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. Its output voltage can be adjusted by the internal register to optimize efficiency according to the type of LEDs (their forward voltage). This reduces current mirror power dissipation and improves overall efficiency. The STLED524 also includes an internal LDO regulator, which can provide a supply voltage for an additional circuitry. Maximum current, provided by each current mirror, is adjusted by RSETresistor. Current of each LED (dot) can be dimmed in 255 steps due to settings of internal registers.The STLED524 features PWM dimming in 255 steps. Automatic slope function is also supported. Cycle time and slope time can be adjusted for each LED (dot) separately.Two patterns can be stored in internal registers. The automatic scrolling of the display content is possible in 4 ways.
