The TPS92630QPWPRQ1 is an IC component manufactured by Texas Instruments. It is specifically designed for automotive lighting applications and offers comprehensive features that make it a highly versatile and efficient solution.
One of the key features of the TPS92630QPWPRQ1 is its ability to drive multiple LEDs with high precision. It supports up to 28 series-connected LEDs with efficient current balancing, which ensures uniform lighting across the entire array. This makes it well-suited for demanding automotive lighting applications, such as headlights and daytime running lights.
To enable accurate current control, the TPS92630QPWPRQ1 utilizes a constant current buck controller with a wide feedback voltage range. This allows it to support various LED configurations and adapt to different operating conditions. Additionally, it offers a wide input voltage range of 4.5V to 65V, enabling it to handle a range of voltage fluctuations in automotive systems.
The integrated diagnostics feature of the TPS92630QPWPRQ1 is another highlight. It provides comprehensive fault monitoring, enabling early detection of any abnormalities in the LED array. This helps ensure the system's reliability and enables proactive maintenance. The diagnostic information can be communicated via an I2C interface, allowing easy integration with the vehicle's diagnostic system.
The TPS92630QPWPRQ1 also includes an adaptive overvoltage protection feature that safeguards the LEDs against voltage spikes, which may occur during load dump or cold-crank scenarios
