LND8925
60 V Led Driver, 12 Channel, 40mA
w/ High Speed Two Wire Interface & Daisy Chain
GENERAL DESCRIPTION
The LND8925 is a 12 channel LED driver featuring up to 60V
high side connections at 0-40mA (average) per channel. Each
channel is controlled by a high speed digital interface, allowing
flexible grey scale control.
Utilizing a slim aspect ratio, the LND8925 is suitable for slim
Tape Carrier Packaging (TCP) and Chip On Glass (COG)
applications. A token structure, 8MHz, data bus combined with
two global state bits enables a cascade design capable of high
speed data loading with a minimized footprint.
The LND8925 is available in a slim 16.5mm x 2mm bumped die or
TCP package. Other package options are available, please call
factory for more information. The LND8925 is rated for a junction
temperature of -40C to 150C.
The LND8925 enables true cathode to ground connections due to its
high side topology, while simultaneously allowing operating voltages
up to 60V. This simplifies fanout and grounding requirements
compared to other solutions.
