Overview
The TLC59025IDBQR is a low-power, 16-channel constant current LED sink driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and delivers up to 45 mA per channel. The device features an internal boost converter capable of generating output voltages up to 17 V, enabling the driving of high-voltage LED strings. It utilizes a serial interface for data input and includes thermal shutdown protection. The component is housed in a QSOP-24 package and supports operation across an extended temperature range from -40°C to +125°C.
Feature Summary
- Integrates an internal boost converter to drive high-voltage LED loads without external inductors
- Provides 16 individually controllable constant current sinks with adjustable brightness control
- Includes thermal shutdown circuitry to protect the device during overtemperature conditions
Applications
- LED backlighting systems for displays
- General-purpose LED lighting applications
- Portable electronic devices requiring efficient LED driving
Procurement Notes
Verify the specific suffix 'DBQR' against the manufacturer's official datasheet to confirm the package type (QSOP-24) and tape-and-reel quantity specifications. Ensure that the required operating temperature range and electrical parameters align with the design requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits that require multiple constant current outputs driven by a single controller. The integrated boost topology simplifies board layout by eliminating external power components. Consider the thermal performance and maximum output voltage limits relative to the connected LED string configuration.
Part Context
This part belongs to the TLC59xx series of LED drivers from Texas Instruments, designed for low-power applications. It complements other variants in the family that may offer different channel counts or control interfaces, providing a scalable solution for various LED illumination needs.
Replacement Considerations
Consult the official TI cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains compatibility with the QSOP-24 footprint and meets the same electrical specifications for voltage, current, and thermal management.
