Introduction, features, and applications of Texas Instruments LP5810 4-channel RGBW LED driver

2/14/2024 9:05:00 AM

Summary: When lighting LEDs, it provides an ultra-low conventional operating current of 0.4mA (typical).

LP5810 Texas Instruments

The Texas Instruments LP5810 4-channel RGBW LED driver is an ultra-low conventional operating current, typically 0.4mA when lighting LEDs. These drivers are compatible with logic pins in 1.8V, 3.3V and 5V voltage ranges. The LP5810 LED driver features autonomous animation engine control. These LED drivers provide output current per LED that can be adjusted in 256 steps from 0.1mA to 25.5mA or 0.2mA to 51mA. The LP5810 4-channel RGBW LED driver operates over the -40°C to 85°C temperature range. These drivers generate a 6MHz clock signal and synchronize lighting effects between multiple devices. The LP5810 driver is ideal for portable and wearables, gaming and home entertainment, Internet of Things (IoT), networking and industrial HMI.
