LED Driver IC datasheet and documents for LP5812DDSDR

LP5812DDSDR

LED Driver IC Overview

The LP5812DDSDR is a Texas Instruments LED driver IC featuring four linear constant-current outputs. It operates within a supply voltage range of 2.7V to 5.5V, supporting output voltages from 0V to 5.5V. Each channel provides an adjustable output current ranging from 100µA to 25.5mA. The device supports analog and PWM dimming methods and utilizes an I2C interface for control. It is housed in an 8-WSON package with dimensions of 3x3mm and functions reliably across a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

Four independent linear constant-current channels for precise LED control
Integrated I2C interface for digital configuration and status monitoring
Supports both analog and pulse-width modulation (PWM) dimming techniques
Compact 8-WSON surface-mount packaging for space-constrained designs

LED Driver IC Applications

Portable electronic device backlighting systems
General-purpose indicator lighting circuits
Embedded LED illumination modules

LED Driver IC Procurement Notes

Verify the specific suffix DDSDR against official datasheets to confirm the 8-WSON package type and tape-and-reel orientation. Ensure compatibility with I2C bus voltage levels and check thermal dissipation requirements for the small form factor. Confirm RoHS compliance status through manufacturer documentation prior to integration.

LED Driver IC Selection Notes

Select this component when four independently controllable low-current LED channels are required in a minimal footprint. It is suitable for applications needing flexible dimming via I2C rather than complex multiplexing. Consider the linear topology limitations regarding heat dissipation at higher currents compared to switching drivers.

LED Driver IC Part Context

This part belongs to the LP581x series of LED drivers from Texas Instruments, designed for portable electronics. It shares functional similarities with the LP5810 and LP5812AYBHR but differs in package style. The series focuses on providing simple, cost-effective solutions for driving multiple LEDs in consumer devices without requiring external power switches.
