CAT9532  
16-bit Programmable LED Dimmer with I2C Interface  
FEATURES  
DESCRIPTION  
„ 16 LED drivers with dimming control  
„ 256 brightness steps  
The CAT9532 is a CMOS device that provides 16-bit  
parallel input/output port expander optimized for LED  
dimming control. The CAT9532 outputs can drive  
directly 16 LEDs in parallel. Each individual LED may  
be turned ON, OFF, or blinking at one of two  
programmable rates. The device provides a simple  
solution for dimming LEDs in 256 brightness steps for  
backlight and color mixing applications. The CAT9532  
is suitable in I2C and SMBus compatible applications  
where it is necessary to limit the bus traffic or free-up  
the bus master’s timer.  
„ 16 open drain outputs drive 25 mA each  
„ 2 selectable programmable blink rates:  
– frequency: 0.593Hz to 152Hz  
– duty cycle: 0% to 99.6%  
„ I/Os can be used as GPIOs  
„ 400kHz I2C bus compatible*  
„ 2.3V to 5.5V operation  
The CAT9532 contains an internal oscillator and two  
PWM signals that drive the LED outputs. The user can  
program the period and duty cycle for each individual  
PWM signal. After the 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 provide a maximum output  
current of 25mA. The total current sunk by all I/Os must  
not exceed 200mA.  
„ 5V tolerant I/Os  
„ Active low reset input  
„ RoHS-compliant 24-Lead SOIC, TSSOP and  
24-pad TQFN (4 x 4mm) packages  
APPLICATIONS  
„ Backlighting  
„ RGB color mixing  
„ Sensors control  
„ Power switches, push-buttons  
„ Alarm systems
