LP5813BDRRR

LED Driver IC Overview

The LP5813BDRRR is a synchronous boost 4 x 3 matrix RGB LED driver manufactured by Texas Instruments. It integrates an I2C interface and autonomous animation control capabilities. The device operates within an input voltage range of 0.5 V to 5.5 V, requiring a minimum of 1.8 V for start-up. It is housed in a 12-pin WSON (DRR) package with dimensions of 3x3 mm. The component supports analog and PWM dimming with a maximum output current of 50 mA per channel.

LED Driver IC Feature Summary

• Integrates synchronous boost converter topology for efficient RGB LED matrix driving
• Provides autonomous animation control functionality via I2C interface
• Supports combined analog and PWM dimming methods for brightness adjustment

LED Driver IC Applications

• RGB LED matrix display systems
• Portable electronic devices requiring integrated LED drivers
• Automotive interior lighting applications

LED Driver IC Procurement Notes

Verify the specific suffix 'B' against the official Texas Instruments datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the WSON-12 package footprint aligns with the PCB layout. Confirm RoHS compliance status through the manufacturer's product information page before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when a compact solution for driving 4x3 RGB matrices is required. The integrated boost converter eliminates external inductor complexity. Verify that the system power supply meets the 1.8 V start-up threshold. Consider the I2C address configuration if multiple drivers are used on the same bus line.

LED Driver IC Part Context

This part belongs to the LP5813 family of LED drivers from Texas Instruments. It is designed as a drop-in replacement for similar matrix drivers but offers integrated boost regulation. The DRR suffix indicates the reel packaging format. It complements other TI display drivers like the LP5899 series which handle different matrix configurations.

LED Driver IC Replacement Considerations

Check for LP5813CDRRR or LP5813BDWR variants for potential pin-compatible alternatives. Verify functional equivalence regarding the boost converter efficiency and animation memory depth. Ensure the alternative part number maintains the same 12-pin WSON package dimensions.
