Overview
The TLC5922DAP is a Texas Instruments LED display driver featuring 16 constant-current sink channels in a 32-pin HTSSOP package. It operates on a supply voltage range of 3 V to 5.5 V with a maximum supply current of 65 mA. The device supports linear dimming and includes dot correction capabilities for uniform brightness. It functions within an operating temperature range of -20°C to +85°C.
Feature Summary
- Provides 16 independent constant-current sink outputs for LED control
- Integrates dot correction circuitry to ensure consistent luminance across all segments
- Supports serial data input via standard digital interfaces for efficient pin usage
Applications
- LED signage and display panels
- General-purpose LED lighting systems
- Backlighting applications requiring precise current regulation
Procurement Notes
Verify the specific suffix (e.g., DAP) against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure that the component meets RoHS compliance requirements for your target market. Cross-reference the ordering number with authorized distributors to confirm availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when a high channel count with integrated brightness correction is required. It is suitable for designs needing linear dimming control without external PWM generators. Consider the thermal performance and power dissipation limits inherent to the HTSSOP-32 package when designing the PCB layout for heat management.
Part Context
This part belongs to the TLC5922 series, designed specifically for driving large arrays of LEDs. It simplifies system design by combining multiple driver functions into a single IC, reducing the overall component count and board space compared to discrete solutions or simpler drivers lacking correction features.
Replacement Considerations
The TLC5922DAPR is a reel-packaged alternative within the same family. Verify interface compatibility and pinout consistency before substitution. No other direct cross-model replacements are confirmed in public documentation.
