Product details

Supply range and logic compatibility

The I2C interface is referenced to VDD.

The linear output stage dissipates heat proportional to (V_supply - V_LED) × I_channel × number_of_channels; at high voltage drops and full load, the package temperature rise can exceed 40°C above ambient. For continuous operation near the upper temperature limit, derate the per-channel current or reduce the number of active channels.

Marked as Active with ROHS3 compliance.

Frequently asked questions

Is PCA9685BS equivalent to PCA9685?

The PCA9685BS,118 is the surface-mount 28-HVQFN variant of the PCA9685 family. The base part PCA9685 is also available in other packages (e.g., TSSOP); electrical functionality is identical across the family, but the package and thermal performance differ. Verify the package before substituting.
