The PCA9532PW,112 from NXP Semiconductors is a 16-bit I2C-bus and SMBus compatible I/O expander specifically designed for dimming LEDs. It supports Red/Green/Blue (RGB) color mixing and backlight applications with 256 discrete brightness steps.
This device features an internal oscillator that allows for two user-programmable blink rates and duty cycles, enabling precise control over LED brightness. The open-drain outputs can directly drive LEDs with a maximum sink current of 25 mA per bit and 200 mA per package. Any unused I/O bits can be utilized as general-purpose parallel inputs/outputs (GPIOs).
The PCA9532PW,112 operates over a voltage range of 2.3 V to 5.5 V and supports clock frequencies up to 400 kHz. It is housed in a 24-TSSOP package suitable for surface mounting. The operating temperature range is -40°C to 85°C.
Key features include 16 LED drivers, programmable blink rates, and I2C dimming control. It also includes an active LOW reset pin and Power-On Reset (POR) for initialization.
