Overview
The TLC5917IN is an eight-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 supports a maximum output current of 120 mA per channel. The device features a boost topology with a maximum output voltage of 20 V and functions at a clock frequency up to 30 MHz. Packaged in a PDIP-16 format, it ensures reliable operation across temperatures from -40°C to +125°C. Key integrated protections include thermal shutdown capabilities.
Feature Summary
- Provides eight independent constant-current outputs for precise LED control
- Integrates thermal shutdown protection to safeguard against overheating
- Supports serial interface communication for data and clock input
Applications
- LED lighting driver circuits
- General-purpose LED indicator arrays
- Display backlighting systems
Procurement Notes
Verify the specific package type and temperature rating during procurement. Confirm that the component meets all required electrical specifications for the target application environment. Ensure compatibility with existing serial interface protocols used in the design. Check for any specific handling requirements associated with the PDIP-16 packaging.
Selection Notes
Select this component when eight channels of constant-current sinking are required. Consider the 120 mA limit per channel for load sizing. Evaluate the boost topology requirement for driving higher voltage LED strings. Verify that the operating temperature range aligns with the intended deployment conditions.
Part Context
This part belongs to the TLC5917 series of LED drivers. It shares functional similarities with other members like the TLC5917QDRQ1 but differs in package and automotive qualification status. The IN suffix denotes the standard industrial-grade PDIP-16 variant.
Replacement Considerations
The TLC5917QDRQ1 offers similar functionality but includes AEC-Q100 automotive qualification and uses a SOIC-Narrow-16 package. Direct substitution requires verifying package footprint compatibility and checking if automotive grade certification is necessary for the application.
