Overview
The TLC5922DAPRG4 is a 16-channel constant-current sink LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 5.5V and supports a data transfer rate of 30 MHz. The device features 128-step adjustable constant-current sinks for dot correction on each channel, with an output current capability up to 80mA per channel. It utilizes a 32-pin HTSSOP package and functions within an operating temperature range of -20°C to +85°C.
Feature Summary
- Provides 16 channels of constant-current sinking with individual On/Off states
- Enables precise brightness control through 128-step adjustable dot correction per channel
- Supports high-speed serial data input at 30 MHz for efficient display driving
Applications
- LED display systems requiring dot correction
- General-purpose LED lighting applications
- Signage and indicator panels
Procurement Notes
Verify the specific suffix 'RG4' confirms RoHS compliance and lead-free status as per Texas Instruments documentation. Ensure the HTSSOP-32 package dimensions match your PCB footprint requirements. Confirm the operating temperature grade (-20°C to +85°C) aligns with your environmental specifications before finalizing procurement.
Selection Notes
Select this component when 16 independent constant-current outputs are required without PWM dimming complexity. It is suitable for designs needing hardware-based dot correction to ensure uniform LED brightness. Consider the 30 MHz interface speed if high refresh rates are necessary. Verify that the linear regulation approach fits your thermal management strategy compared to switching alternatives.
Part Context
This part belongs to the TLC5922 family of LED drivers from Texas Instruments. It serves as a specialized solution for managing multiple LEDs in display arrays. The device simplifies design by integrating current regulation and correction logic into a single compact package, reducing external component count compared to discrete solutions.
Replacement Considerations
The TLC5922DAPR is a non-RoHS compliant alternative within the same series. Verify pin compatibility and electrical specifications when substituting. No direct functional equivalents with different interfaces were identified in public documentation.
