ALED1642GW規(guī)格書詳情
Description
The ALED1642GW is a monolithic, low voltage,
low current power 16-bit shift register designed for
LED panel displays. The ALED1642GW
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 ALED1642GW. The auto power-shutdown
and auto power-on features (selectable) allow the
device to save power without external
intervention.
Thermal management includes an
overtemperature data alert and output thermal
shutdown (170 °C). The high clock frequency is
up to 30 MHz and it makes the device suitable for
high data rate transmission. A selectable gradual
output delay reduces the inrush current, whereas
the selectable SDO synchronization feature works
when the device is used in daisy-chain
configuration. The supply voltage range is
between 3 V and 5.5 V.
