Overview
The TLC5924DAPR is a Texas Instruments LED display driver featuring sixteen constant-current sink channels. It utilizes a serial interface for data input and includes an internal oscillator to eliminate the need for external components. The device supports PWM dimming across all channels with adjustable frequency, enabling precise brightness control. Packaged in a 32-pin HTSSOP, it operates within a supply voltage range of 3V to 5.5V.
Feature Summary
- Provides sixteen individually addressable constant-current sink channels for uniform LED illumination
- Integrates a serial interface compatible with standard shift register protocols for simplified system connectivity
- Features an internal oscillator that removes the requirement for external timing components
Applications
- LED matrix displays
- Bar graph indicators
- Numeric displays
Procurement Notes
Verify the specific package variant against the datasheet specifications before integration. Confirm that the operating temperature range aligns with the intended environmental conditions. Ensure the serial interface timing requirements are met by the host controller to guarantee reliable data transmission during operation.
Selection Notes
Select this component when a high channel count is required without complex multiplexing. It is suitable for designs needing independent current regulation per channel. Consider the thermal performance of the HTSSOP package if multiple channels operate at maximum load simultaneously.
Part Context
This part belongs to the TLC592x series of LED drivers from Texas Instruments. These devices are designed for applications requiring multiple output channels with individual current control. The series offers various packaging options to accommodate different board space constraints and thermal management needs.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains identical electrical characteristics and interface compatibility.
