CAT9532:I/O Port Expander, I2C / SMBus, 16-bit, w/LED Dimming
The CAT9532 is a I/O Port Expander, I2C / SMBus, 16-bit, w/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.
