  • The LED2472G is a monolithic, low voltage, low current power 24-bit shift register designed for LED panel displays with particular features oriented to indoor and outdoor LED screen billboards. The LED2472G guarantees 20 V of output driving capability, allowing several LEDs to be connected in series. The device is configured in 3 groups (red, green and blue) of 8 independently-controlled channels. The LED current can be separately regulated for each color within the range from 4 mA to 72 mA. This range is divided into two sub-ranges and the current can be adjusted within each range in 64 steps of resolution (6 bits per color). A single external resistor is required. All the controls and the shift register data are accessible via serial interface. A single 24-bit configuration register is used to choose features and settings to fit the application. The LED failure detection circuit checks 3 different conditions that can occur at the output line: short to GND, short to LED power supply rail or open channel. The auto power shutdown and auto power-on feature (selectable) allows the device to save power without any external intervention. Thermal management includes overtemperature flag and the output thermal shutdown (170 °C). The high clock frequency of up to 30 MHz makes the device suitable for high data rate transmission. A selectable gradual output delay reduces the inrush current. The supply voltage ranges from 3 V and 5.5 V.
