Product Overview
The ALED1642GWXTTR is a 16-channel LED Driver with error detection, current gain control and 12/16-bit PWM brightness control. The monolithic low voltage/low current power 16-bit shift register designed for LED panel displays. The ALED1642GW guarantees 20V output driving capability allowing the user to connect several LEDs in series. 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 sub ranges. 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. The auto power-shutdown and auto power-ON features (selectable) allow the device to save power without external intervention.
- 16 Constant current output channels
- Current programmable through external resistor
- 7-bit Global current gain adjustment in two ranges
- Programmable output turn-ON/OFF time
- Error detection mode (both open and shorted-LED)
- Programmable shorted-LED detection thresholds
- Auto power-saving/auto-wakeup
- Thermal management includes an over-temperature data alert and output thermal shutdown (170°C)
