TLC69612RTWR

Overview

The TLC69612RTWR is a Texas Instruments LED lighting driver IC designed for local dimming backlight applications. It features 16 constant current sink channels with integrated SRAM for brightness storage. The device supports a two-wire serial interface and operates within an input voltage range of 3 V to 5.5 V. Key electrical parameters include a maximum output current of 60 mA per channel, a maximum output voltage of 20 V, and a maximum supply current of 3.5 mA. It functions at a working frequency of 20 MHz and is housed in a WQFN-24 package.

Feature Summary

Integrates 16 constant current sinks with dedicated SRAM for individual channel brightness control
Supports local dimming functionality via a two-wire serial interface
Includes hardware-based open and short LED detection capabilities

Applications

Mini-LED matrix local dimming backlights
High-resolution display backlight systems
Automotive infotainment displays

Procurement Notes

Verify the specific suffix RTW to confirm the WQFN-24 package type and reel packaging configuration. Ensure compatibility with the host controller's two-wire serial interface protocol. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range for standard grade devices.

Selection Notes

Select this component when a high channel count with integrated memory is required for complex local dimming patterns. Compare against the TLC69608 or TLC69618 if different current ratings or automotive qualification (AEC-Q100) are needed. Verify that the 20V output compliance voltage meets the forward voltage requirements of the target LED string configuration.

Part Context

This part belongs to the TLC696x family of time-multiplexing local dimming drivers. It shares architectural similarities with the TLC69608 and TLC69618 but offers distinct current drive capabilities. The RTWR designation indicates surface mount packaging suitable for automated assembly processes in consumer and industrial electronics manufacturing.

Replacement Considerations

The TLC69618RTWRQ1 serves as an automotive-grade alternative with higher current capability. For lower current requirements, the TLC69608RTWR is a compatible option within the same package footprint.
