The PCA9532D,118 from NXP Semiconductors is a 16-bit I2C-bus and SMBus I/O expander designed for dimming LEDs. It offers 256 discrete steps for Red/Green/Blue (RGB) color mixing and backlight applications.
This device includes an internal oscillator with two programmable blink rates and duty cycles, allowing for precise control of LED brightness. The LED brightness is managed by adjusting the duty cycle, enabling the LED to appear at different brightness levels or blink at periods up to 1.69 seconds. Outputs are open-drain and can directly drive LEDs with a maximum sink current of 25 mA per bit and 200 mA per package.
Unused I/O bits can function as General Purpose Parallel Input/Output (GPIO) for various applications such as ACPI power switches, sensors, push-buttons, and alarm monitoring. The PCA9532D,118 supports a clock frequency up to 400 kHz and operates within a voltage range of 2.3 V to 5.5 V. It is housed in a 24-SOIC package and is suitable for surface mounting.
Key features include 16 LED drivers with programmable rates, 256 brightness steps, an internal oscillator, and an I2C-bus interface compatible with SMBus. It also has an active LOW reset input and noise filters on SCL/SDA inputs.
