PCA9958 24-Bit 63mA Current LED Drivers with SPI
NXP Semiconductors PCA9958 24-Bit 63mA Current LED Drivers with SPI are 24-channel SPI serial bus 63mA LED drivers with a supply voltage range of 2.7V to 5.5V. These devices are optimized for dimming and blinking RGBA LEDs. Each LED features its own 8-bit resolution fixed frequency operating at 31.25kHz with an adjustable duty cycle of 0% to 100% for brightness control. The additional PWM controller has a fixed frequency of 122Hz and an adjustable frequency of 15Hz duty cycle from 0% to 99.6% for dimming and blinking control.
