PCA9685PW,118 NXP LED Driver | 28-TSSOP | 16-Channel, 12-bit PWM, I2C

Product Overview

The PCA9685PW,118 from NXP Semiconductors is a 16-channel, 12-bit PWM (Pulse Width Modulation) LED controller with an I2C-bus interface. It is designed to control LEDs and other devices requiring PWM signals, such as servos and motors. Each channel has its own 12-bit resolution (4096 steps) and can be set to a specific duty cycle and frequency. The device operates from a 2.3V to 5.5V supply and features an internal oscillator that eliminates the need for external components. The 28-TSSOP package allows for compact designs, making it ideal for space-constrained applications.
