Shenzhen Mingjiada Electronics Co., Ltd. [Supply] PCA9958HNY (NXP) LED Drivers: 63mA/5.5V, 24-Channel SPI Serial Bus, Constant Current LED Driver

PCA9958HNY 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.

PCA9958HNY operates with a supply voltage range of 2.7V to 5.5V and the constant current sink LED outputs allow up to 5 V for the LED supply. The output peak current is adjustable with an 8-bit linear DAC from 250 µA to 63.75 mA with REXT = 1 kΩ.

PCA9958HNY has built-in open, short load and overtemperature detection circuitry. The error information from the corresponding register can be read via the 4-wire serial bus. Additionally, a thermal shutdown feature protects the device when internal junction temperature exceeds the limit allowed for the process.

PCA9958HNY is designed to use 4-wire read/write serial bus with higher data clock frequency (up to 10MHz).
