TLC5924DAP

Overview

The TLC5924DAP is a 16-channel LED display driver manufactured by Texas Instruments, housed in a 32-pin HTSSOP package. It operates within a supply voltage range of 3 V to 5.5 V and draws a maximum power supply current of 65 mA. The device supports serial interface control for channel selection and brightness adjustment. It features fault detection capabilities, including open LED detection, and provides a power good/error flag output. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates 16 independent constant-current sink channels for direct LED control
• Includes diagnostic features such as open LED detection and error flag signaling
• Supports serial data input for simplified interface with microcontrollers

Applications

• LED matrix displays
• Bar graph indicators
• Status indicator arrays

Procurement Notes

Verify the specific suffix DAP corresponds to the HTSSOP-32 tube packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to guarantee alignment with current electrical specifications and pinout definitions.

Selection Notes

Select this component for designs requiring multiple low-current LED outputs controlled via a serial interface. It is suitable for applications where thermal management is limited due to its linear regulation architecture. Consider the 32-pin HTSSOP footprint constraints during PCB layout. Evaluate the 65 mA supply current against system power budgets. This part is appropriate for general-purpose lighting indication rather than high-power illumination tasks.

Part Context

This device belongs to the TLC5924 series of LED drivers from Texas Instruments. It shares the functional family with variants like the TLC5924DR, differing primarily in packaging type. The series is designed for cost-effective control of large numbers of LEDs using minimal I/O pins. It complements other Texas Instruments driver solutions by offering integrated diagnostics without external components.

Replacement Considerations

The TLC5924DR serves as a reel-pack alternative within the same series. Verify pin compatibility and electrical parameters before substitution. No direct cross-manufacturer equivalents are confirmed in public documentation.
