Description
General part information
LED1642GW Series
The LED1642GW is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The LED1642GW guarantees 20 V output driving capability allowing the user to connect several LEDs in series. In the output stage, sixteen regulated current sources provide from 3 mA to 40 mA 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 (four different values available) 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 (selectable) allow the device to save power without external intervention.
