software control of each color
• 2 External hardware address pins allow
connecting up to 4 devices
• Broadcast slave address allows configuring
multiple devices simultaneously
• Auto-increment allows writing or reading
consecutive registers within one transmission
• Up to 400-kHz fast-mode I2C speed
2 Applications
LED lighting, indicator lights, and fun lights for:
• Smart speaker (with voice assistant)
• Smart home appliances
• Video doorbell
• Electronic smart lock
• Smoke and heat detector
• STB and DVR
• Smart router
• Handheld device
3 Description
In smart homes and other applications that use
human-machine-interaction, high-performance RGB
LED drivers are required. LED animation effects such
as flashing, breathing and chasing that greatly
improves user experience, and minimal system noise
is essential.
The LP50xx device is an 9- or 12-channel constant
current sink LED driver. The LP50xx device includes
integrated color mixing and brightness control, and
pre-configuration simplifies the software coding
process. Integrated 12-bit, 29-kHz PWM generators
for each channel enable smooth, vivid color for LEDs,
and eliminate audible noise.

5 Description (continued)
The LP50xx device controls each LED output with a 12-bit PWM resolution at 29-kHz switching frequency, which
helps achieve a smooth dimming effect and eliminates audible noise. The independent color mixing and intensity
control registers make the software coding straightforward. When targeting a fade-in, fade-out type breathing
effect, the global R, G, B bank control reduces the microcontroller loading significantly. The LP50xx device also
implements a PWM phase-shifting function to help reduce the input power budget when LEDs turn on
simultaneously.
The LP50xx device implements an automatic power-saving mode to achieve ultra-low quiescent current. When
channels are all off for 30 ms, the device total power consumption is down to 10 µA, which makes the LP50xx
device a potential choice for battery-powered end equipment.
