Overview
The TLC5922DAPG4 is a 16-channel constant-current sink LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports a data transfer rate of 30 MHz. Each channel provides an output current capability of up to 80 mA, with a maximum power dissipation of 3.9 W. The device features dot correction for uniformity and is housed in a 32-HTSSOP package. It functions within an operating temperature range of -20°C to +85°C.
Feature Summary
- Provides 16 channels of constant-current sinking for LED control
- Includes per-channel dot correction to ensure display uniformity
- Supports high-speed serial data input at 30 MHz
- Features CMOS-compatible logic levels for interface
Applications
- LED signage displays
- General lighting systems
- Backlight applications
Procurement Notes
Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the required 32-HTSSOP form factor. Ensure the operating environment stays within the specified -20°C to +85°C temperature range. Validate that the supply voltage does not exceed the 5.5 V maximum limit during operation.
Selection Notes
Select this component when a 16-channel constant-current solution is required for LED arrays. It is suitable for designs needing precise current control without external resistors. Consider the 30 MHz interface speed if high refresh rates are necessary. Ensure the system can accommodate the thermal requirements associated with the 3.9 W power dissipation rating.
Part Context
This part belongs to the TLC5922 series of LED drivers from Texas Instruments. It is designed as a linear driver IC for managing multiple LED segments. The G4 suffix indicates specific manufacturing or compliance attributes defined by the original equipment manufacturer. It serves as a dedicated controller for segment-based LED displays.
Replacement Considerations
The TLC5922DAP is a compatible alternative within the same product family. Both parts share identical electrical characteristics and pin configurations. Verify that any substitute maintains the same HTSSOP-32 package dimensions for board compatibility.
