Overview
The TLC5911PZP is a 16-output linear shift register LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and delivers an output current of up to 80 mA per channel. The device features a data transfer rate of 20 MHz and maintains a channel-to-channel accuracy of typically ±4%. It supports an operating temperature range from -20°C to 85°C and is housed in a 100-pin HTQFP package measuring 14x14 mm.
Feature Summary
- Integrates a linear shift register architecture for sequential LED control
- Provides individual channel current regulation with specified accuracy
- Supports high-speed serial data input for efficient signal processing
Applications
- Segmented LED display systems requiring uniform brightness control
- High-density LED matrix drivers for visual indicators
- Industrial control panels utilizing multi-segment lighting elements
Procurement Notes
Verify the specific suffix PZP corresponds to the 100-HTQFP package configuration. Confirm the operating temperature grade matches the -20°C to 85°C specification required for your environment. Ensure compatibility with the 4.5 V to 5.5 V supply rail before integration.
Selection Notes
Select this component when a high pin count solution is necessary for driving multiple LED segments independently. The 80 mA output capability suits medium-brightness applications without external transistors. Consider the 100-pin footprint constraints during PCB layout planning.
Part Context
This part belongs to the TLC5911 family of LED drivers, designed for applications requiring precise current control across numerous outputs. The PZP designation specifically identifies the plastic quad flat package variant, distinguishing it from other thermal or mechanical configurations within the same functional series.
Replacement Considerations
Consult official substitution lists for equivalent 16-output LED drivers with similar current ratings and package dimensions. Verify pin compatibility and electrical specifications before swapping components in existing designs.
