STMicroelectronics LED1642GW 16-Channel LED Drivers
STMicroelectronics LED1642GW 16-Channel LED Drivers are low voltage 40mA 16-channel drivers designed for LED panel displays. The LED1642GW guarantees 20V output driving capability allowing the user to connect several LEDs in series. In the output stage, sixteen regulated current sources provide from 3mA 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 sub-ranges. The brightness can be adjusted separately for each channel through a 12/16-bit grayscale control. The supply voltage range is between 3V and 5.5V.
