The PCA9633D16,112 is a 4-bit LED driver from NXP Semiconductors, designed for Red/Green/Blue/Amber (RGBA) color mixing applications. It operates via an I2C-bus interface and offers individual 8-bit resolution PWM controllers for each of its four LED outputs, capable of 25mA sink current at 5V. These controllers operate at 97 kHz with adjustable duty cycles from 0% to 99.6% for precise brightness control.
A fifth 8-bit resolution Group PWM controller is also included, operating at 190 Hz with an adjustable frequency. This group controller allows for synchronized dimming or blinking of all LEDs with the same value. The device supports a supply voltage range of 2.3V to 5.5V, with outputs being 5.5V tolerant.
The PCA9633D16,112 is available in a 16-SOIC package, suitable for surface mounting. Its Fast-mode Plus (Fm+) I2C-bus compatibility allows for higher frequency and more densely populated bus operations. The active LOW Output Enable (OE) pin provides asynchronous control of the LED outputs, useful for external PWM control or setting all outputs to a defined state.
This LED driver is optimized for applications requiring color mixing and dynamic lighting effects. Its programmable I2C addresses allow for flexible control of multiple devices on the same bus, minimizing I2C-bus commands for complex lighting arrangements.
