Overview
The TPIC1533DWR is a high-voltage LED driver integrated circuit manufactured by Texas Instruments. It features three independent constant-current sinks capable of driving up to 200mA per channel with an output voltage range extending to 40V. The device utilizes a serial interface for data input and includes built-in diagnostics such as open-load detection and over-temperature protection. Packaged in a TSSOP-20 (DW) format, it is designed for robust operation in automotive and industrial lighting applications requiring precise current control and fault monitoring.
Feature Summary
- Three independent constant-current sink channels providing precise LED brightness control
- Integrated diagnostic capabilities including open-load detection and thermal shutdown protection
- Serial interface compatibility for straightforward data input and configuration
Applications
- Automotive exterior lighting systems
- Industrial indicator arrays
- High-brightness LED signage
Procurement Notes
Verify the specific suffix 'DWR' corresponds to the TSSOP-20 package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the supplier provides valid traceability records for automotive-grade components.
Selection Notes
Select this component when designing circuits requiring multiple high-side or low-side LED drivers with integrated fault reporting. Compare against similar parts based on maximum output voltage, current accuracy, and diagnostic feature sets. Ensure the operating temperature range meets the specific environmental requirements of the target application.
Part Context
This part belongs to the TPIC15xx series of high-voltage LED drivers from Texas Instruments. These devices are engineered to simplify LED control in complex lighting architectures by integrating power stages and logic into a single compact package. The series supports various pin counts and channel configurations to accommodate different design constraints.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical specifications before substituting. Common alternatives may include other high-voltage LED drivers from major manufacturers, but functional equivalence must be confirmed via datasheet comparison.
