Additional Infomation About Product

LED1642GW 16 channel LED driver with error detection current gain control and 12/16-bit PWM brightness control Datasheet - production data Applications Full color/monochrome large displays LED signage QSOP-24 Description The LED1642GW is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The LED1642GW TSSOP24 guarantees 20 V output driving capability allowing TSSOP24 (exposed pad) 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 Features through an external resistor and can be adjusted by a 7-bit current gain register in two subranges. 16 constant current output channels The brightness can be adjusted separately for Output current: from 3 mA to 40 mA each channel through 12/16-bit grayscale control. Current programmable through external Programmable turn-on and turn-off time (four resistor different values available) improves the low noise generation performance of the system. 7-bit global current gain adjustment in two ranges Open/short error detection mode is available in 12/16-bit PWM grayscale brightness control the LED1642GW. The auto power-shutdown and auto power-on features (selectable) allow the Programmable output turn-on/off time device to save power without external Error detection mode (both open and shorted- intervention. LED) Thermal management includes an Programmable shorted-LED detection overtemperature data alert and output thermal thresholds shutdown (170 C). The high clock frequency is Auto power saving/auto-wakeup up to 30 MHz and it makes the device suitable for high data rate transmission. A selectable gradual Selectable SDO synchronization on the CLK output delay reduces the inrush current, whereas falling edge the selectable SDO synchronization feature works Gradual output delay (selectable) when the device is used in daisy-chain Supply voltage: 3 V to 5.5 V configuration. The supply voltage range is between 3 V and 5.5 V.
