TLC69612QRTWRQ1

Overview

The TLC69612QRTWRQ1 is a 16-channel automotive local dimming backlight LED driver featuring time-multiplexing capabilities. It integrates constant current sinks with SRAM for brightness storage and supports PWM dimming at 60 mA per channel. The device operates on a two-wire serial interface with a high-speed daisy chain connection. It functions within an input voltage range of 3 V to 5.5 V and withstands output voltages up to 20 V. Designed for AEC-Q100 Grade 1 qualification, it ensures reliability in temperatures from -40°C to +125°C.

Feature Summary

• Integrates 16 constant current sinks with corresponding SRAM for individual pixel brightness storage
• Supports high-speed daisy chain interface via a two-wire serial connection
• Enables independent 16-bit PWM control for precise local dimming applications

Applications

• Automotive interior ambient lighting systems
• Mini-LED matrix local dimming backlights
• High-resolution automotive display backlight units

Procurement Notes

Verify the specific suffix RTWRQ1 matches the required WQFN package and reel quantity. Confirm AEC-Q100 Grade 1 compliance is necessary for your target vehicle tier. Ensure the design supports the 3 V to 5.5 V supply range. Check that the host controller can handle the high-speed daisy chain timing requirements. Validate thermal management for the -40°C to +125°C operating environment.

Selection Notes

Select this component when 16 independently controllable channels are required for automotive displays. It is suitable for designs needing integrated SRAM to reduce external memory usage. Choose this driver for applications demanding high-speed serial communication to minimize pin count. It is ideal for mini-LED implementations requiring precise local dimming control without complex external circuitry.
