NXP PCA9685PW,112 16‑ch 12‑bit PWM I2C LED Controller TSSOP28

The NXP PCA9685PW,112 is a compact, 28-pin TSSOP surface-mount LED driver, offering 16 independent 12-bit PWM channels with fine brightness control via an I²C interface, perfect for precision backlighting, LED arrays, or servo control in global B2B and technical applications. Adjustable from approx. 24 Hz up to 1.5 kHz (up to 1 MHz for Fast‑mode Plus variants), allowing versatility across lighting and motor control tasks.

Core Features and Benefits of the Product

• Temperature Range: Durable from –40 °C to +85 °C, meeting industrial operating conditions.
• High‑Resolution Control ensures flicker‑free LED dimming and smooth servo operation.
• I²C Expandability: Up to 62 devices can share a bus, allowing for control over 992 PWM outputs, making it ideal for large-scale LED arrays or robotics applications.
• Minimal MCU Overhead: The built-in clock frees the microcontroller from continuous output handling.

Use Cases

Ideal for LED backlighting, display signage, robotics, IoT lighting systems, and mixed-signal circuitry, especially where fine PWM control and I²C interfacing are paramount.
