Features
■
256 discrete brightness steps for easy LED dimming and color mixing
■
two programmable blinking rate between 0.625 sec and 1.6 sec for
CAT9532; 0.02sec and 6.4 sec for CAT9552
■
eliminates repeated commands to turn on/off LEDs, reducing I
2
C traffic
■
drives up to 16 LEDs; any bit that is not used to drive an LED can be used
as a GPIO
■
25mA sink current per bit (max 200mA per device)
■
each port can be individually turned on, off, or programmed to blink
■
during power-up or when a manual reset (hardware reset) is asserted,
all outputs are set to off-mode
■
built in noise filter for SDA/SCL inputs
■
0-400KHz clock frequency
Applications
■
LED dimming
■
LCD backlighting
■
celluar phones
Notes:
1. Available in standard and “green” packages.
2. CAT7311 is pin compatible with the MAX7311. All other products are pin compatible with Philips (replace PCA with CAT to order).
