The 25 mA per-channel current rating is the sink capability at the output pin; the actual LED current is set by an external series resistor between the supply and the LED anode, while the driver pulls the cathode to ground. Because the PWM is integrated, the host MCU is free from real-time timing loops — a single I²C write programs the blink phase and duty cycle for all eight channels, and the driver runs autonomously.","metaTitle":"NXP PCA9551D,118 LED Driver, 8-Ch PWM, 25mA, 16-SOIC","metaDescription":"NXP PCA9551D,118 LED driver IC, 8-channel PWM power switch, 25mA per output, 16-SOIC, -40°C to +85°C.
