TLC69601QPWPRQ1

Overview

The TLC69601QPWPRQ1 is an automotive-grade LED lighting driver IC designed for local dimming mini-LED backlight applications. It features a 16-channel constant current sink architecture with integrated SRAM for brightness storage. The device operates within a supply voltage range of 3 V to 5.5 V and supports a maximum output voltage of 50 V. Each channel delivers a constant current of 60 mA. The component utilizes a PWM topology and functions at a working frequency of 20 MHz. It is housed in an HTSSOP-28 package and is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates 16 constant current sinks with dedicated SRAM for individual channel brightness control.
• Designed specifically for automotive local dimming mini-LED matrix backlight systems.
• Supports high-voltage outputs up to 50 V per channel for flexible LED string configurations.

Applications

• Automotive LCD local dimming backlight drivers
• Mini-LED matrix lighting systems
• High-contrast automotive display modules

Procurement Notes

Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging, temperature grade, and automotive qualification status. Confirm that the specific ordering code matches the required HTSSOP-28 package and tape-and-reel specifications. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance and functional safety certifications relevant to the intended automotive application.

Selection Notes

Select this component when designing automotive displays requiring precise per-pixel or per-zone brightness control via SRAM storage. Ensure the system design accommodates the 60 mA per-channel current limit and the 50 V maximum output voltage capability. Verify compatibility with the host controller interface and confirm that the thermal management strategy supports the specified operating temperature range of -40°C to +125°C.

Part Context

This device belongs to the Texas Instruments TLC696x1-Q1 family of 16-channel constant current sink drivers. It shares architectural similarities with other members like the TLC69600 and TLC69662 series but is optimized for automotive local dimming applications. The Q1 suffix indicates automotive qualification, while the PWPRQ1 designation specifies the HTSSOP-28 package and reel packaging configuration.

Replacement Considerations

Direct substitutes within the same family include the TLC69600QPWPRQ1, though it offers a lower 30 mA output current and 20 V max output voltage. For higher channel counts, consider the TLC69662QPWPRQ1 or TLC69668QPWPRQ1. Always verify pin-to-pin compatibility and electrical parameter differences before substitution.
