CAT9552  
16-Channel I2C-bus LED Driver with  
Programmable Blink Rate  
FEATURES  
DESCRIPTION  
„ 16 LED drivers with On/Off and programmable  
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.  
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  
The CAT9552 contains an internal oscillator and two  
PWM signals, which drive the LED outputs. The user  
may program the period and duty cycle for each  
individual PWM signal. After an initial set-up command  
to program the Blink Rate 1 and Blink Rate 2 (frequency  
and duty cycle), only one command from the bus master  
is required to turn each individual open drain output ON,  
OFF, or cycle at Blink Rate 1 or Blink Rate 2. Each open  
drain LED output can sink a maximum current of 25mA.  
The total continuous current sunk by all I/Os must not  
exceed 200mA per package.  
„ 5V tolerant I/Os  
„ Active low reset input  
„ RoHS-compliant 24-Lead SOIC, TSSOP and  
24-pad TQFN (4 x 4mm) packages  
APPLICATIONS  
„ Office machines  
„ Appliance control panels  
„ Alarm systems
