Auto-Increment Allows Writing or Reading Consecutive Registers Within One Transmission
Up to 400-kHz Fast-Mode I2C Speed
Description for the LP5018
In smart homes and other applications that utilize human-machine-interaction,high-performance RGB LED drivers are required. LED animation effects such as flashing, breathing,and chasing greatly improve user experience, and minimal system noise is essential.
The LP50xx device is an 18- or 24-channel constant current sink LED driver. The LP50xxdevice includes integrated color mixing and brightness control, and pre-configuration simplifiesthe software coding process. Integrated 12-bit, 29 kHz PWM generators for each channel enablesmooth, vivid color for LEDs, and eliminate audible noise.
The LP50xx device controls each LED output with a 12-bit PWM resolution at 29-kHzswitching frequency, which helps achieve a smooth dimming effect and eliminates audible noise. Theindependent 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 reducesthe microcontroller loading significantly. The LP50xx device also implements a PWM phase-shiftingfunction to help reduce the input power budget when LEDs turn on simultaneously.
The LP50xx device implements an automatic power-saving mode to achieve ultralow quiescentcurrent. 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.

Select a carrier option
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
