The PCA9532BS,118 from NXP Semiconductors is a 16-bit I2C-bus and SMBus I/O expander designed for LED dimming applications. It supports Red/Green/Blue (RGB) color mixing and backlight control with 256 discrete brightness steps. The device features an internal oscillator with two user-programmable blink rates and duty cycles, allowing for precise control of LED brightness.
Each of the 16 open-drain outputs can directly drive LEDs with a maximum sink current of 25 mA per bit and 200 mA per package. Bits not used for LED driving can function as General Purpose Parallel Input/Output (GPIO) expansion. The PCA9532BS,118 operates over a voltage range of 2.3 V to 5.5 V and supports clock frequencies up to 400 kHz.
This component is housed in a 24-HVQFN package and is suitable for surface mounting. It operates within a temperature range of -40°C to 85°C. The device includes an active LOW hardware reset pin and Power-On Reset (POR) for initialization.
Applications include backlighting and general LED control where precise brightness adjustment and blinking functionality are required. The I2C interface simplifies integration into existing bus systems.
