Product details

Supply range and logic compatibility

Runs on a 2.3 V to 5.5 V supply. The I2C interface is referenced to VDD. The 28-HVQFN (6x6 mm) package with exposed pad requires a thermal land on the PCB for adequate heat sinking.

Temperature grade and environment

Rated for -40°C to 85°C ambient, covering industrial enclosures, outdoor signage, and automotive cabin lighting. 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.

Lifecycle and sourcing

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.
