Драйверы систем светодиодного освещения LED2472GBTR

Драйвер светодиода , 24 выхода, постоянный ток, 3В-5.5В (Vin), 30МГц, 19В/72мА, HTQFP-48

The LED2472GBTR is a 24-channel LED Driver with error detection and gain control. The 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 20V 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 colour within the range from 4 to 72mA. 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 colour). 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.

• 8 x 3 Independently controlled channels (RGB)
• Current programmable through external resistor
• 7-bit Global current gain adjustment in two ranges
• Error detection mode (both open and shorted-LED)
• Programmable shorted-LED detection thresholds
• Auto power-saving
• auto-wakeup
• Thermal shutdown and thermal flag
• Up to 30MHz CLK 4 wires interface
• 20V Current generators rated voltage
