Overview
The TCA6507ZXUR is a low-voltage LED driver manufactured by Texas Instruments, designed for intensity control and shutdown capabilities. It features seven open-drain outputs capable of directly driving LEDs with a maximum current of 40 mA per channel. The device supports I2C and SMBus interfaces for digital control. It operates within a supply voltage range of 1.65 V to 3.6 V and includes programmable fading rates. The component is housed in a 12-pin UFBGA package.
Feature Summary
- Supports I2C and SMBus communication protocols for digital control
- Features seven independent open-drain output channels
- Provides programmable intensity control and fading rates
- Includes dedicated shutdown functionality
Applications
- LED backlighting systems
- Indicator lighting applications
- Portable electronic devices requiring low-voltage LED control
Procurement Notes
Verify the specific package variant, as the ZXUR suffix denotes a BGA package distinct from other TCA6507 variants. Confirm interface compatibility with the host controller's I2C or SMBus bus speed requirements. Ensure the supply voltage remains within the specified 1.65 V to 3.6 V range during operation.
Selection Notes
Select this component when a low-voltage solution with multiple LED channels is required. It is suitable for applications needing precise intensity control via digital interfaces. Consider the thermal performance of the BGA package for high-density designs. Verify that the 40 mA output current meets the load requirements.
Part Context
This part belongs to the TCA6507 family of LED drivers from Texas Instruments. The family offers various packages and pinouts while maintaining core functionality. The ZXUR variant specifically utilizes a Microstar Junior BGA package, differing from QFN or SOIC options available in the same series.
Replacement Considerations
The TCA6507RUER is a documented substitute within the same product family. Both parts share identical electrical specifications and functionality. Differences are limited to the physical package type, with the RUER using an X2QFN format instead of the BGA configuration.
