Product Overview
LED1642GWXTTR is a 16 channel LED driver with error detection current gain control and 12/16-bit PWM brightness control. It is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The LED1642GW guarantees 20V output driving capability. In the output stage, sixteen regulated current sources provide from 3 to 40mA constant current to drive the LEDs. The current is programmed through an external resistor and can be adjusted by a 7-bit current gain register in two subranges. The brightness can be adjusted separately for each channel through 12/16-bit grayscale control. Programmable turn-on and turn-off time improves the low noise generation performance of the system. Open/short error detection mode is available in the LED1642GW. The auto power-shutdown and auto power-on features allow the device to save power without external intervention. Typical applications include full colour/monochrome large displays and LED signage.
