LED Driver has 16 open drain outputs to drive 25 mA each.
July 10, 2008 -
Available in 4 x 4 mm, 24-lead SOIC, TSSOP, and 24-pad TQFN package, CAT9552 I2C/SMBus drives up to 16 LEDs in programmable flashing or on/off modes. LED driver/blinker is designed with internal oscillator and 2 programmable on/off or blink rate timers, adjustable from 0.02-5.8 sec. Featuring I/Os that can be used as general purpose I/Os, it is suited for advertising point-of-sale signage with flashing LEDs, and any type of consumer or industrial equipment with on/off LED indicators.
16-Channel I2C LED Blinker from Catalyst Semiconductor Provides Simple Solution for Flashing and "On/Off" LED Applications
CAT9552 drives up to 16 LEDs in parallel, with programmable "on/off" and "blink" control functions
SANTA CLARA, Calif., July 2, 2008 - Catalyst Semiconductor, Inc. a supplier of analog, mixed-signal and non-volatile memory semiconductors, has added a 16-channel I2C/SMBus LED driver/blinker to its line of bus products. The CAT9552 drives up to 16 LEDs in either programmable flashing or "on/off" modes. The CAT9552 is ideal for applications including advertising point-of-sale signage with flashing LEDs, and any type of consumer or industrial equipment with "on/off" LED indicators.
The CAT9552 is designed with an internal oscillator and two programmable "on/off" or "blink" rate timers, adjustable from 0.02 to 5.8 seconds. This oscillator and its two timers reduce overall parts count and substantially reduce the I2C bus traffic, which would normally occur if traditional bus expanders were used. An added benefit of the CAT9552 is that I/Os not used for controlling LEDs can be used as general-purpose I/Os (GPIOs).
Product Features
o 16 open drain outputs drive 25mA each
o Two programmable "on/off" and "blink" rate timers (adjustable from 0.02 to 5.8 seconds)
o I/Os can be used as general purpose I/Os
o Packaging: 24-lead SOIC, TSSOP and 24-pad TQFN (4 x 4mm)
Price and Availability
Pricing for the CAT9552 LED driver/blinker is $1.00 each, in 10,000 piece quantities. Samples are available now. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
