TCA6507PWR

Overview

The TCA6507PWR is a low-voltage LED driver IC featuring seven independent output channels. It supports I2C and SMBus interfaces for digital control, operating within a supply voltage range of 1.65 V to 3.6 V. Each channel provides an open-drain output capable of sourcing up to 40 mA. The device operates at frequencies up to 400 kHz and delivers outputs up to 5.5 V. It is housed in a 16-pin TSSOP package and functions across temperatures from -40°C to +85°C.

Feature Summary

Supports I2C and SMBus communication protocols for digital control
Provides seven independent open-drain output channels
Enables linear dimming capabilities via interface commands

Applications

LED backlighting systems
General LED lighting applications
Portable electronic devices requiring low-power illumination

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-pin TSSOP footprint matches the target PCB design constraints. Ensure compatibility with the system's I2C bus voltage levels and address configuration before integration into the final product design.

Selection Notes

Select this component when a multi-channel LED driver with digital interface control is required. It is suitable for designs needing individual channel management without complex external logic. Consider the 40 mA per channel limit and the 3.6 V maximum supply voltage when sizing the power delivery network and load requirements for the application.

Part Context

This part belongs to the TCA6507 series of LED drivers manufactured by Texas Instruments. It is designed for low-voltage applications requiring multiple independently controllable outputs. The series focuses on providing efficient light control through standard serial interfaces, making it a common choice for consumer electronics and portable device illumination subsystems.
