TPS92662AQPHPRQ1

TPS92662AQPHPRQ1 is an automotive-grade LED matrix manager developed by Texas Instruments for advanced automotive lighting applications. Designed for adaptive driving beam (ADB) headlights and intelligent front-lighting systems, this device provides individual LED control, programmable PWM dimming, and integrated LED bypass switches to support precise illumination management and dynamic lighting patterns.

The TPS92662AQPHPRQ1 features 12 integrated LED bypass switches arranged in four sub-strings, supporting flexible LED configurations. It offers programmable 10-bit PWM dimming for accurate brightness adjustment and dynamic LED control. Its multi-drop UART communication interface enables coordination between multiple devices, making it suitable for complex automotive lighting architectures.

Additional features include an integrated 8-bit ADC for temperature compensation and LED binning measurements, an I2C interface for external EEPROM communication, and LED open-circuit and short-circuit detection. Programmable clock settings also help engineers optimize electromagnetic interference (EMI) performance in automotive electronic systems.

The TPS92662AQPHPRQ1 operates with an input voltage range of 4.5V to 60V and supports an ambient operating temperature range of -40°C to +125°C. It is AEC-Q100 qualified and comes in a 48-pin HTQFP package measuring 7.00 mm × 7.00 mm.

Typical applications include automotive LED headlights, adaptive driving beam systems, glare-free high beams, intelligent front lighting, sequential turn signals, and animated daytime running lights. With precise LED pixel control, integrated bypass switching, and automotive-grade reliability, the TPS92662AQPHPRQ1 provides a flexible solution for advanced automotive lighting designs.
