Description:

16-Channel I2C-bus LED Driver

Features

* 16 LED drivers with On/Off and programmable blink rate control
* 2 selectable, programmable blink rates:
* frequency: 0.172Hz to 44Hz
* duty cycle: 0% to 99.6%
* 16 open drain outputs drive 25mA each
* I/Os can be used as GPIOs
* 400kHz I2C b

Applications

* where it is desireable to limit the bus traffic or free-up the bus master’s internal timer. Three address pins allow up to eight CAT9552 devices to occupy the same bus. The CAT9552 contains an internal oscillator and two PWM signals, which drive the LED outputs. The user may program the period and d
