PCA9685BS,118 NXP LED Driver | 28-HVQFN（6x6） | 16-Channel, I2C, PWM

Product Overview

The PCA9685BS,118 from NXP Semiconductors is a 16-channel, 12-bit PWM Fm+ I2C-bus LED controller. Designed for high-performance LED control, it operates from a 2.3V to 5.5V supply and features an internal oscillator requiring no external components. The device is housed in a 28-pin HVQFN (6x6 mm) package, making it suitable for space-constrained applications. Each channel has a programmable PWM frequency up to 1.6 kHz, and the outputs can be configured as open-drain with 25 mA sink capability. The I2C interface supports standard (100 kHz), fast (400 kHz), and fast-mode plus (1 MHz) speeds, with six hardware-selectable slave addresses allowing up to 96 channels on a single bus.
