CAT9532
16-bit Programmable LED
Dimmer with I 2 C Interface
Description
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 I 2 C and SMBus compatible
applications where it is necessary to limit the bus traffic or free ? up the
bus master ’s timer.
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 25 mA. The total current sunk by all I/Os
must not exceed 400 mA.
