com CAT9552 16-Channel I2C-bus LED Driver with Programmable Blink Rate 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 bus compatible 2.
3V to 5.
5V operation 5V tolerant I/Os Active low reset input RoHS-compliant 24-Lead SOIC, TSSOP and 24-pad TQFN (4 x 4mm) packages DESCRIPTION The CAT9552 is a 16-channel, parallel input/output port expander optimized for LED On/Off and blinking control.
Each individual LED may be turned ON, OFF, or set to blinking at one of two programmable rates.
The CAT9552 is compatible with I2C and SMBus 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...
