TLC69610-Q1

The TLC69610-Q1 is a high-performance, automotive-grade LED driver IC designed for robust and efficient control of multiple LEDs in demanding environments. It features 16 independent current sinks, each capable of driving up to 25 mA with precise current regulation, ensuring consistent brightness and long-term reliability across varying operating conditions. The device supports both analog and digital dimming methods, offering flexibility in brightness control—ranging from 0.1% to 100% duty cycle—with minimal flicker or noise. This IC integrates advanced diagnostics including open-load detection, short-circuit protection, and thermal shutdown functionality, which enhance system safety and fault tolerance. Its wide supply voltage range (4.5 V to 28 V) makes it suitable for various automotive power systems, while its AEC-Q100 Grade 1 qualification ensures reliability under extreme temperature conditions (-40°C to +125°C). The serial interface supports SPI-compatible communication at up to 10 MHz, enabling fast configuration and real-time monitoring of all channel outputs. The TLC69610-Q1 includes built-in current mirror circuits for accurate current matching across channels, minimizing color variation in multi-LED arrays—critical for applications such as automotive lighting where visual uniformity is essential. Additionally, it offers programmable turn-on/off delays and individual channel enable/disable functions, allowing fine-grained control for complex lighting patterns or adaptive signaling systems. Designed specifically for automotive applications, this device is ideal for interior lighting, instrument clusters, ambient lighting, and exterior signal lamps like position lights, brake lights, and turn indicators. Its low quiescent current and efficient architecture contribute to reduced power consumption, aligning with modern vehicle energy efficiency standards. The compact 32-pin QFN package further simplifies integration into space-constrained designs without compromising thermal performance or electrical robustness. With comprehensive protection mechanisms and support for both high-side and low-side configurations, the TLC69610-Q1 delivers reliable operation in harsh automotive environments. Its scalable architecture allows for easy expansion to drive more LEDs by daisy-chaining multiple devices, making it a versatile solution for evolving vehicle lighting systems.
