The CAT9532 is a CMOS device that provides 16-bitparallel input/output port expander optimized for LEDdimming control. The CAT9532 outputs can drivedirectly 16 LEDs in parallel. Each individual LED maybe turned ON, OFF, or blinking at one of twoprogrammable rates. The device provides a simplesolution for dimming LEDs in 256 brightness steps for
backlight and color mixing applications. The CAT9532is suitable in I2C and SMBus compatible applicationswhere it is necessary to limit the bus traffic or free-upthe bus master’s timer.
