Add To BomPCA9685PW General Description
The PCA9685PW is a 16-channel, 12-bit PWM (Pulse Width Modulation) controller integrated circuit (IC) manufactured by various semiconductor manufacturers, including NXP Semiconductors (formerly Philips Semiconductors) and others. This IC is commonly used to control and drive LEDs and servos in various electronic and robotics applications.
Features
16 Channels: The PCA9685PW can independently control and drive up to 16 channels of PWM outputs, making it suitable for applications that require precise control of multiple LEDs or servos.
12-Bit Resolution: It offers a high-resolution PWM output with 12-bit resolution, allowing for smooth and precise control of the connected devices.
Frequency Control: The PCA9685PW allows you to set the PWM frequency, which can range from approximately 24 Hz to 1526 Hz, depending on the specific configuration.
I2C Interface: It communicates with a microcontroller or other devices through the I2C (Inter-Integrated Circuit) serial interface, which simplifies the control and configuration of the PCA9685PW.
Internal Oscillator: The IC typically includes an internal oscillator for generating the PWM signals, eliminating the need for an external clock source.
LED Lighting Control: The PCA9685PW is often used for LED lighting applications, such as dimming and color control, in automotive, architectural, and decorative lighting systems.
Servo Motor Control: It can also be used for precise control of servo motors in robotics and automation projects, providing accurate positioning control.
Multiple PCA9685s Daisy-Chaining: Multiple PCA9685PW ICs can be daisy-chained on the same I2C bus, allowing for the control of a large number of channels if needed.
Output Enable Pins: Each channel typically has an output enable pin, which allows you to disable or enable individual channels as needed.
Compact Package: The PCA9685PW is typically available in a compact surface-mount package, making it suitable for compact and space-constrained designs.
