PCA9958 Product details

Description

PCA9958 is a daisy-chain SPI-compatible 4-wire serial bus controlled 24-channel constant current LED driver optimized for dimming and blinking 63 mA Red/Green/Blue/Amber (RGBA) LEDs.

Features

24 LED drivers. Each output programmable at:.
Off.
On.
8 bits programmable LED brightness.
8 bits programmable group dimming/blinking mixed with individual LED brightness.
Programmable LED output delay to reduce EMI and surge currents.
Gradation control for all channels.
Each channel can be assigned to one of six gradation control groups.
Programmable gradation time and rate for ramp-up and/or ramp-down operations.
